Solution

The correct option is A Hydrogen is evolved.
When calcium carbonate reacts with nitric acid, it gives carbon dioxide, calcium nitrate and water.

$C a C O_{3} + 2 H N O_{3}$ $\to$ $C a (N O_{3})_{2} +$ $H_{2} O +$ $C O_{2}$
Calcium carbonate Nitric Acid Calcium Nitrate Water Carbon dioxide

Hence the correct option is B.
