Answer »Answer: (c)
As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun.
This can happen only at the new moon when the Sun and the Moon are in conjunction as seen from Earth. In a total eclipse, the disk of the Sun is fully obscured by the Moon.
In partial and annular eclipses only part of the Sun is obscured. The moon blocks out the bulk of the sun allowing us to see the chromosphere and corona.
