Five is the theoretical maximum number of solar eclipses in one calendar year; generally 4 partial eclipses and one total or annular eclipse. This configuration happens about every 200 years or so. Interestingly, there will be four solar eclipses in 2011; all will be partial eclipses, visible (if at all) only from polar regions. The last time there were five solar eclipses in a year was in 1935; the next time will be in 2206.
On average there are as many solar eclipses as there are lunar ones. But each lunar eclipse can be seen from half the Earth, while a solar eclipse can only be seen from a relatively small strip of the Earth's surface. So in any one place it seems that solar eclipses are rare.
There are generally two solar eclipses and two lunar eclipses each year. Because solar eclipses cover a very narrow stripe across the Earth, solar eclipses SEEM TO BE rare - in one particular location. There can be several CENTURIES between total solar eclipses in the same spot. On the other hand, it can be just a few years. There's a town in Illinois that will have two total solar eclipses only 8 years apart, in 2017 and 2024.
There are generally two lunar eclipses and two solar eclipses each year. Sometimes you will see two partial eclipses instead of one total eclipse; in 2011, there will be four partial solar eclipses, and no total or annular solar eclipses. Since lunar eclipses happen on the Moon, they are visible from the entire night half of the Earth. Solar eclipses, when the Moon's shadow hits the Earth, affect very small areas of the Earth, and so they seem to be more rare. The next total lunar eclipse will happen on December 21, 2010, and will be visible from any point in North America.

They're not all that rare; there's one about every year somewhere.
As total solar eclipses are very rare and spectacular, the sight of them is much sought after.

Yes, these are called partial eclipses.

Most years, there are two solar eclipses. Some years, because of the precise geometry between the Sun, Earth and Moon, we have two partial eclipses instead of one total or annular eclipse. Very rarely, there are FOUR solar eclipses in one calendar year.Because each eclipse affects only a tiny area of the Earth, it is fairly rare for one location to experience two total solar eclipses in the same decade, and it isn't uncommon for there to be centuries between total solar eclipses for any specific spot on the Earth.

'C' (the missing one) is the correct choice.
This is known as a solar eclipse, where the moon passes between the Earth and the sun, blocking the sun's light. There are different types of solar eclipses, including total, partial, and annular eclipses, depending on the alignment of the sun, moon, and Earth. Solar eclipses are rare and can only be seen from specific locations on Earth.
About two per year, since the Moon formed. So, around 4000 solar eclipses (and 4000 lunar eclipses) since the year 1. You can check the list of all eclipses since the year 2000 BC on the NASA Eclipse Web Page at the link below.
