The correct answer is:
$\mathrm{AgNO}_3+\mathrm{NH}_4 \mathrm{OH}$
Butyne-1 has the terminal hydrogen atom which reacts with ammonical silver nitrate easily and liberate hydrogen.
$2 \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{C} \equiv \mathrm{CH}+\mathrm{Ag}_2 \mathrm{O} \longrightarrow \underset{\text{white ppt}}{\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{C} \equiv \mathrm{CAg}+\mathrm{H}_2 \mathrm{O}}$
Hence butyne- 1 and butyne- 2 are distinguished by $\mathrm{AgNO}_3+\mathrm{NH}_4 \mathrm{OH}$
$2 \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{C} \equiv \mathrm{CH}+\mathrm{Ag}_2 \mathrm{O} \longrightarrow \underset{\text{white ppt}}{\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{C} \equiv \mathrm{CAg}+\mathrm{H}_2 \mathrm{O}}$
Hence butyne- 1 and butyne- 2 are distinguished by $\mathrm{AgNO}_3+\mathrm{NH}_4 \mathrm{OH}$
