Solution

The correct option is A $H g S O_{4}$ and dil. $H_{2} S O_{4}$
Like alkanes and alkenes, alkynes are also immiscible in water and do not react with water. However, one molecule of water adds to an alkyne on warming with $H g S O_{4}$ and dil. $H_{2} S O_{4}$ at 333 K to form a carbonyl compound.

So, the correct answer will be option (a).
