Yes, these are called partial eclipses.
C
'C' (the missing one) is the correct choice.
The corona during total solar eclipses.
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.

Actually solar eclipses are slightly more common, but a solar eclipse, and especially the total phase, can only be seen in a relatively narrow strip of Earth.
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.
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.
About twice a year.
On earth there are 2 eclipses, Lunar and Solar eclipses
There will be four partial solar eclipses in 2011, and NO total solar eclipses. You can view the catalog of all eclipses from 2000 BCE to 3000 AD on the NASA Eclipse Web Page.
For the Earth as a whole, partial solar eclipses are slightly more commonthan total ones.For any one location on Earth, partial solar eclipses are far more commonthan total ones.
