Answer 1

it is letter d! :).

Answer 2

D.) The gravitational pull of the Moon on Earth's oceans.

Step-by-step explanation:

A.) is incorrect because waves caused by the moon's gravitational pull. Waves and tides are essentially the same thing.

B.) is incorrect because climate change only has a small, indirect effect on the tides (i.e., rising sea levels).

C.) is incorrect because while the gravitational pull of the Sun affects the tides to some extent, it is nowhere near as influential as the Moon's gravitational pull.

D.) is correct because the gravitational forces between the Moon and the Earth are the primary cause of the tides.
