Mark the correct choice as:

(a) If both assertion and reason are true and reason is the correct explanation of assertion.

(b) If both assertion and reason are true but reason is not the correct explanation of assertion.

(c) If assertion is true but reason is false.

(d) If assertion is false but reason is true.

Assertion: Distance is a scalar quantity.

Reason: Distance has magnitude but no direction.

Answer 1

Explanation for assertion statement

1. Distance is a scalar quantity.
2. Distance is the total length of the path coved by the body.

Explanation for reason statement

1. Distance has magnitude but no direction.
2. It is not a vector quantity because it has no direction but only magnitude.

Therefore, both assertion and reason are true and reason is the correct explanation of assertion.

Hence, option (a) is the correct answer.
