Solution

The correct option is A $1$ atmospheric
A barometer is used to measure the atmospheric pressure in terms of height of mercury column. The mercury column takes a height of $76 c m$ under normal atmospheric pressure. So, pressure exerted by $76 c m$ high mercury column is considered as $1$ atmospheric pressure.
