Solution

The correct option is C 0.0199
$2 H I ⇋ H_{2} + l_{2}$

$\begin{matrix} I n i t i a l n o o f m o l e s - & 2 m o l e s & 0 & 0 a t e q u i l i b r i u m & 2 m o l e s - 0.44 & 0.22 & 0.22 \end{matrix}$

$K_{c} = \frac{[H_{2}] [l_{2}]}{[H I]^{2}} = \frac{0.22 \times 0.22}{{1.56}^{2}} = 0.0199$
