Solution

The correct option is B $C H_{2} = C H - O H$
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.

$C_{2} H_{2} H g S O_{4} / H_{2} S O_{4} - -------- \to 333 K (C H_{2} = C H - O H) ⇌ C H_{3} C H O$

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