A
The moon makes one complete revolution around Earth.
B
Earth makes one complete revolution around the sun.
C
Earth makes one complete spin on its axis.
D
The sun makes one complete spin on its axis.
Explanation: 

Detailed explanation-1: -The motion around the sun along its orbit is called a revolution. The amount of time it takes for a single trip around the sun is called a period of revolution. The period for the Earth to revolve around the sun is 365.24 days or one year.

Detailed explanation-2: -So in one year, Earth travels about 584 million miles (940 million km). Since speed is equal to the distance traveled over the time taken, Earth’s speed is calculated by dividing 584 million miles (940 million km) by 365.25 days and dividing that result by 24 hours to get miles per hour or km per hour.

Detailed explanation-3: -A year on Earth is approximately 365 days. Why is that considered a year? Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time.

Detailed explanation-4: -Earth also travels on an elliptical orbit around the Sun. And it takes one year to make a complete trip. In one year Earth makes one revolution around the Sun.
