Solution

The correct option is A HgSO4 and dil. H2SO4
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 HgSO4 and dil. H2SO4 at 333 K to form a carbonyl compound.

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