C
${H_2}S$ is evolved
D
${H_2}$ is evolved

✓

Answer

Correct option: B.

$P{H_3}$ is evolved

b
When alluminium Phospide reacts with $H _2 SO _4$ it gives $PH _3$ ( Phosphine $), Al _2\left( SO _4\right)_3$

$2 AlP +\text { dil. } 3 H _2 SO _4 \rightarrow Al _2\left( SO _4\right)_3+2 PH _3 \text {. }$
