Solution

The correct option is C ammoniacal AgNO3
CH3CH=CHCHO+[O]CH3CH=CHCOOH

on analyzing above reaction we find that we have to use that oxidizing agent which retain the double bond and oxidized CHO into COOH.

Now,

we have Option A,B,and D are strong oxidizing agent which can oxidised CHOas well as double

Thus, we will use mild oxidising agent ammonical AgNO3(Tollens reagent) to carry out above reaction.
