Read the following statements (A) and (R) and choose the appropriate option in the context of tides.
Assertion (A) : During the full moon and new moon days the tides are highest.
Reason (R): The Sun, the Moon and the Earth are in the same line and the strong gravitational pull exerted by the Sun and the Moon causes the highest tide.

Correct option is A

During the full moon and new moon days, the tides are indeed highest. These tides, called spring tides, occur when the Sun, the Moon, and the Earth are in a straight line. The combined gravitational pull of the Sun and the Moon on the Earth's waters results in higher high tides and lower low tides. Therefore, both the assertion and the reason are true, and the reason is the correct explanation of the assertion.
