This equation cannot be correct. Hence, option (c) is the correct option.

#### Work Step by Step

First-order in $H_{2}$ implies that the power of $[H_{2}]$ is 1 in the rate law. But in the given rate equation, the power of $[H_{2}]$ is 2. Therefore, this equation cannot be correct. Hence, option (c) is the correct option.
