${\mathrm{PH}}_4\mathrm{I}+\mathrm{KOH}\to \mathrm{KI}+{\mathrm{H}}_2\mathrm{O}+\mathrm{X}\left(\mathrm{g}\right)$ Correct statement for X is:

${\mathrm{PH}}_4\mathrm{I}+\mathrm{KOH}\to \mathrm{KI}+{\mathrm{H}}_2\mathrm{O}+\underset{\left(x\right)}{{\mathrm{PH}}_3\left(\mathrm{g}\right)}$

${\mathrm{PH}}_3\left(\mathrm{g}\right)$ is colorless, have Rotten fish smell

The following explosion reaction is found,

${\mathrm{PH}}_3+{\mathrm{HNO}}_3\to$
