Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Tides indicate the regular and periodic rise and fall in the sea level.
Reasons (R) : Tides are caused by the gravitational pull of the moon and sea level.
In the light of the above statements, choose the correct answer from the options given below :

Assertion(A): True. Tides indeed indicate the regular and periodic rise and fall in the sea level, which is a well-documented natural phenomenon.

Reason (R): False. While tides are caused by the gravitational pull of the moon and the sun, the reference to "sea level" as a cause is incorrect. The moon's gravitational pull plays the most significant role, and the sun's gravitational pull contributes as well. Sea level, however, is not a causal factor but rather the feature affected by tides.

The gravitational forces of the moon and the sun act on Earth's water bodies, causing tides. The sea level rises and falls as a result of these forces; it does not itself cause the tides. Thus, while the assertion is correct, the reason is factually inaccurate.

We can say that (A) is true but (R) is false

Therefore the correct answer is option C.
