Question

In the following questions, a statement of assertion followed by the reason is given. Choose the correct answers out of the following choices:

Assertion: When two persons talk on the moon, they cannot hear each other.

Reason: Sound requires a material medium to propagate.

• A. Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.
• B. The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.
• C. Assertion is true but the Reason is false.
• D. The statement of the Assertion is false but the Reason is true.
• E. Both the statements are false.

Answer 1

The correct option is A

Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

1. When two persons talk on the moon, they cannot hear each other.
2. Actually, the sound is a mechanical wave, which needs a medium to travel.
3. As it is a type of energy transfer that needs particles to be propagated, that's why it requires a material medium to propagate.
4. Thus, both the assertion and the reason are correct and the reason is the correct explanation of assertion.
5. Hence, the correct option is A.
