Answer

Correct option: A.

Silver acetylene

a
Silver acetylide is fomed, when the acetylene reacts with ammoniacal $AgNO _3$.

$C _2 H _2+2 AgNO _3+2 NH _4 OH \rightarrow C _2 Ag _2+2 NH _4 NO _3+2 H _2 O$

It is called Tollen's Test. The silver acetylide forms a white ppt. This test is used to determine the presence of a triple-bond in hydrocarbons.
