Which two events must happen at the same time to cause a solar eclipse A The moon passes a point where Earth is directly between the sun and the moon
B The moon passes a point directly between the sun and earth
C The moon is at a full-moon phase of the lunar cycle
D The moon is in the new phase of the lunar cycle

B The moon passes a point directly between the sun and earth

Explanation:

During solar eclipse, the moon passes a point directly between the sun and the earth thereby casting a shadow on the earth.

An eclipse is a phenomenon whereby an astronomical body obscures the path of light to another thereby casting a shadow on the other.

Lunar eclipse occurs when the earth comes in between the sun and the moon.

The right choice here is obviously B.
