The correct options are
A Life would not have been possible.
D There would be no day and night.
If Earth did not rotate on its axis, one side would always face the Sun while the other side would be away from the Sun. Thus, one side would become very hot and the other side would become very cold. Ultimately, life would not have been possible under such circumstances. However, the formation of seasons and the occurrence of leap years take place due to the revolution of the Earth and not due to the rotation of the Earth.
