Organ because of all he different parts to it.
It's also hard because you need big hands and you need a lot of concentration to make sure you play the right notes e.g. flats, sharps, natures - you also have to make sure you play the right cord, other wise it sounds bad.
A point of view from someone who plays all three instruments - arguably the violin is the most difficult as the notes are not "right there", as they are with any keyboard instrument. You need a good ear to hear the correct notes and to identify the correct placement of one's fingers on the strings in order to attain the correct pitch.

The piano can make lower notes than a violin because a violin is a very high pitched musical instrument. I would say another thing you can do on a piano that you can't do on the violin is the fact that you can play seconds, thirds, fourths and fifths on the piano.
