How does earth rotation cause day and night?

a) as earth rotates toward the east, the sun appears to rise in the west and set in the east.

b) as earth rotates toward the east, the sun appears to rise in the east and set in the west

c) earth rotates in a clockwise direction, which makes the sun appear in the sky during the day.

d) earths rotation does not cause day and night; its revolution does

I believe the answer is B. Definitely not D or A, and C doesn't makes sense.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
