Answer:
Option A
Explanation:
Statement (A) Sulphur vapour is paramagnetic is correct statement as sulphur vapour has formula $S_{2}$ , i.e, similar to $O_{2}$ and $O_{2}$ has two unpaired electrons in its anti-bonding molecular orbitals
Statement (B) Reaction of HCl (dil.) with finely divided iron forms $FeCl_{3}$ and $H_{2}$ gas isa wrong statement as the whole reaction in as follows :
$Fe+2HCl(dil.)\rightarrow FeCl_{2}+H_{2}(g)$
The $H_{2}$ (g) produced will prevent the formation of $Fe^{3+}$ (i.e, $FeCl_{3}$)
Hence, option (a) is the correct answer
