Solution

The correct option is B Mercury
Mercury is the most preferred liquid for measuring the atmospheric pressure. Mercury is preferred in barometer because mercury does not stick with the glass tube and the height (=76 cm) upto which it rises (while measuring atmospheric pressure) is measurable.
