As we have learnt,

Hydration of Alkynes occur by the Markovnikov addition of a water molecule followed by tautomerisation into Ketone.

\\ CH_3C\equiv C-CH_2-CH_3\overset{H_2SO_4,HgSO_4}{\longrightarrow}CH_3C(OH)= CHCH_{2}-CH_3\rightleftharpoons CH_3-CO-CH_{2}-CH_{2}-CH_3

Therefore, option (3) is correct.
