Question

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:

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true but (R) is not the correct explanation of (A)
• C. (A) is true but (R) is false
• D. (A) is false but (R) is true

Answer 1

The Correct Option is A

The question presents two statements: an assertion and a reason, and asks us to evaluate whether these statements are true and if the reason properly explains the assertion.

1. Assertion (A): "Tides indicate the regular and periodic rise and fall in the sea level."
   This statement is true. Tides are indeed the regular and periodic rise and fall of sea levels caused by the gravitational interactions between the Earth, the moon, and the sun.
2. Reason (R): "Tides are caused by the gravitational pull of the moon and sea level."
   This statement is also partially true. However, it is incomplete because it should correctly state that tides are primarily caused by the gravitational pull of the moon, along with contributions from the sun. The mention of "sea level" is slightly misleading, as it should rather emphasize the gravitational effects.
3. Explanation of the Correct Answer:
   • The assertion is a correct description of what tides are.
   • The reason provided gives a partial explanation toward why tides occur, focusing on gravitational forces, specifically those exerted by the moon. Hence, the reason effectively links to the assertion.
4. Conclusion: Both the assertion and the reason are true; however, the reason is not articulated fully in the statement given but still is fundamentally correct in explaining the phenomenon of tides. Therefore, the appropriate choice is:
   Both (A) and (R) are true and (R) is the correct explanation of (A)
