Solution

The correct option is D
Short column of it can counter balance the atmospheric pressure.

The atmospheric pressure measured by mercury barometer is the pressure equal to that at the bottom of the mercury column given by $h ρ g$ .
Due to high value of $ρ$ the same pressure can be measured for smaller value of $h$ .
