Statement (A) : Only one side of the moon is visible to us on Earth.
Statement (B) : The moon moves around the Earth in about 27 days and takes exactly the same time to complete 1 spin.

Select the correct option from the given alternatives.

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

Answer: A

The answer is both (A) and (B) are true and (B) is the correct explanation of (A).

The moon takes about 27 days to go once around the earth, and it takes almost exactly the same time to turn once on its own axis. Because its rotation and revolution keep pace, the same face of the moon is always turned towards the earth, which is why we see only one side of it.

So (A) is true, (B) is true, and (B) is precisely the reason for (A). The options saying that one statement is false, or that (B) does not explain (A), are therefore wrong.
