Q. Select the correct statement:

$P H_{3}$ is reduces $A g N O_{3}$ to metallic Ag.

Organic tissues turn $A g N O_{3}$ black by reducing it to $A g$ .

$A g CN$ is soluble in $K CN$ .

All are correct statements.

$(A)$ $A g N O_{3} + P H_{3} \to A g ↓ H N O_{3} + H_{3} P O_{3}$

$(B)$ $AgN (O)_{3} \to O r g ani c t i ss u e (p ro t i e n s) Ag ↓ (black)$

(C) $Ag^{+} + 2 KCN \to [Ag (CN)_{2}]^{-} + 2 K^{+}$
