Solution

The correct option is D Both Assertion and Reason are incorrect
On moon there is no atmosphere, so the atmospheric pressure on moon is zero. Therefore the barometer height will be zero.
Also, value of $g$ on moon's surface is $1 / 6$ the value of $g$ on earth's surface.
So, both the statements are incorrect.
