Solution

The correct option is D $C_{2} H_{4}$
A compound responds to Baeyer's test but does not give white precipitation when treated with ammonical silver nitrate solution the compound should be ethylene $C_{2} H_{4}$ .

Alkene & alkyne both give positive Baeyer's test but only terminal alkynes, and not alkenes, give positive test with ammonical silver nitrate [Tollen's reagent].
