(B) The hydration of acetylene $(HC \equiv CH)$ in the presence of dilute $H_2SO_4$ and $HgSO_4$ follows the Kucherov reaction. First,the addition of water across the triple bond forms an unstable enol intermediate,vinyl alcohol $(CH_2=CH-OH)$. This enol undergoes tautomerization to form a stable carbonyl compound,acetaldehyde $(CH_3CHO)$.
