Question

Given below are two statements, one is labelled as Assertion (A) and the other one labelled as Reason (R). Assertion (A): Tides indicate the regular and periodic rise and fall in sea level.
Reason (R): Tides are caused by the gravitational pull of the Moon and the Sun.
In 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.
• E. Both (A) and (R) are false.

Answer 1

The Correct Option is A

Concept: Assertion–Reason evaluation.
Step 1: Check Assertion (A).
Tides are the regular and periodic rise and fall of sea level → True.
Step 2: Check Reason (R).
Tides are caused by the gravitational pull of the Moon and the Sun → True.
Step 3: Check explanation link.
The gravitational pull of the Moon and Sun directly causes the periodic rise and fall of sea level.
Step 4: Conclusion.
Thus, both (A) and (R) are true and (R) correctly explains (A).
