C.  The moon revolves around the Earth and the Earth revolves around the Sun.

Explanation:

The Earth rotates on its axis and it takes 24 hours to do that. The Earth revolves/orbits the Sun and it takes the Earth about 365 days (a year) to do so. The moon revolves round the Earth. It takes the moon about 27.3 days (on average)  to orbit the Earth.

The Earth's rotation on its axis which takes 24 hours to rotate is actually what causes day and night. The path of the Earth around the Sun is called its orbit.

Therefore, the above statement is true.

a. patterns can explain observations.
