Answer 1

Answer: (A)

$(a\to q,r)$ internal alkynes do not react with Tollens reagent, but with $NaN{H}_2$ isomerisation takes place to give terminal alkynes

$(b\to p,q,r)$ Terminal alkynes react with both Tollens reagent and $NaN{H}_2$ to undergo hydrogenation

$(c\to s)(d\to s)$ Alkenes do not react with Tollens reagent or $NaN{H}_2$ or $D_2+N{i}_{2}B$
