Correct answer
BBoth (A) and (R) are correct and (R) is the correct explanation of A.

Step-by-step explanation

It is known that

ω=2πT⇒ω∝1 T

As,
Tmoon ≈27 days
Tearth ≈365 days
⇒ωmoon >ωearth 

Hence, Both the assertion and the reason are correct and the reason is the correct explanation for the assertion.
