Solution

The correct option is B
Volume is decreased

We have $K_{c} = \frac{(n_{N H_{3}} / V)^{2}}{(n_{N_{2}} / V) (n_{H_{2}} / V)^{3}} = \frac{(n_{N H_{3}})^{2}}{(n_{N_{2}}) (n_{H_{2}})^{3}} V^{2}$

The above equilibrium constant $K_{c}$ is a "constant” for a given temperature (also maintained constant unless otherwise mentioned). If V decreases then number of moles of Hydrogen should also decrease.
