Generally the 2nd movement. There can optionally be a 5th movement and there is no fixed temperament, so it's up to the composer.
If a symphony has a slow movement, it is likely to be the second or third, in a four-movement work. There are many exceptions to this.
the second movement
The order of movement in a symphony was broken down into four or five parts. The first part was usually a slow introduction, followed by a slow movement, then a minuet, and finally a rondo or sonata-allegro.
The second movement of a symphony is typically the slow movement. Many (not all) symphonies have one or more movements which are intended to be played at a slow (or slowish) tempo. They are usually of a lyrical character, in contrast to the other movements, which are likely to be faster and/or more vigorous in style. In a four-movement symphony, such a movement is likely to be one of the inner movements; that is, the second or third. The above is such a generalisation, however, that it is better to avoid using the phrase 'the slow movement', which encourages lazy thinking. So-called 'slow' movements can take a range of tempo indications, some of which are not really slow, and all have other characteristics by which they can more usefully be identified. Many such movements are marked Andante, which is not slow but midway between fast and slow. A description such as 'the Larghetto', 'the Adagio', or even just 'the third movement', shows that you have paid some attention to the symphony you are discussing. Bear in mind that by no means all symphonies fall neatly into the four-movement pattern typified by Allegro, Andante, Scherzo, Allegro. Beethoven's Ninth, Schumann's Second, and Elgar's First, to cite but three examples, have an Adagio movement which is placed third. Suk's Asrael symphony has five movements, four of which are marked Andante or Adagio.
The minuet is usually the third movement of a symphony or sonata.
It is Gustav Mahler's Symphony No. 3. The first movement is about 33 minutes.The symphony itself is almost 100 minutes.

The minuet is usually the third movement of a symphony or sonata.
Very commonly, the first movement of a symphony appears in Sonata form. If it is one of the later symphonies (Mozart, for example), it will likely have 4 movements. The second would be some type of slow movement in a binary form. The 3rd would often be a minuet and trio, followed by a closing movement in Sonata form again.
It is Gustav Mahler's Symphony No. 3. The first movement is about 33 minutes.The symphony itself is almost 100 minutes.

a symphony.
The unusual characteristic of Mozart's 36th symphony is that the slow movement had a siciliano character which he only used one other time, in the Paris symphony. However, he continued to use this in his later works, such as symphony No. 40
Beethoven's Symphony No. 5, 1st movement. It is also nicknamed the "Fate" Symphony.
Beethoven's last symphony marked the first time that voices had been used in a symphony. This is now called a choral symphony. Symphony No. 9 is widely considered to be Beethoven's finest work and among the best pieces music ever written by anyone.
As a general rule, a classical symphony has four movements and a classical concerto has three. The nature of their respective first movements and finales is likely to be similar in each case. Each genre will also usually have a slower, more lyrical movement. What a symphony will also have, and a concerto will lack, is a movement cast as a minuet and trio or scherzo and trio.
