B
the Moon rotating on its axis
C
Earth revolving around the Sun
D
Earth rotating on its axis
Explanation: 

Detailed explanation-1: -Which motion occurs at a rate of approximately one degree per day? Earth revolving around the sun.

Detailed explanation-2: -As you know that the earth has two types of motions, namely rotation and revolution. Rotation is the movement of the earth on its axis. The movement of the earth around the sun in a fixed path or orbit is called Revolution.

Detailed explanation-3: -The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40, 075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1, 000 miles per hour.

Detailed explanation-4: -Earth revolves around the Sun at a rate of about 67, 000 miles per hour (107, 000 km/hr or nearly 30 km/s). At the same time, Earth rotates around its axis at about 1, 000 miles per hour (460 m/s or 1, 600 km/hr).
