Solution

The correct option is A Only statement 1 is correct.
Sound waves require a medium to travel. Due to the absence of atmosphere on the surface of the Moon, there is no medium for the sound to propagate. The propagation of sound on the Moon is not related to the surface temperature of the Moon. Also, the Moon's surface is very cold.
Thus, the statement 1 is correct, but the statement 2 is incorrect.
