Solution

The correct option is A HI
When pure, it is non inflammable but becomes inflammable owing to the presence of $P_{2} H_{4} o r P_{4}$ vapours. To purify it from the impurities, it is absorbed in $H I$ to form phosphonium iodide $(P H_{4} I)$ which on treating with $K O H$ gives off phosphine. $P H_{4} I + K O H \to K I + H_{2} O + P H_{3}$
