(b)$\mathrm{FeCl_3(s)}, \mathrm{SO_2(g)}$ and $\mathrm{HCl(l)}$
(c)$\mathrm{FeCl_2(S)}, \mathrm{SO_2(s)}$ and $\mathrm{HCl(g)}$
(d)$\mathrm{FeCl_3(s)}, \mathrm{SO_2(g)}$ and $\mathrm{HCl(g)}$

Answer: D ✓ checked by 4AB · confidence high
Explanation
SOCl₂ is the standard dehydrating agent for hydrated chlorides: FeCl₃·6H₂O + 6SOCl₂ → FeCl₃ + 6SO₂(g) + 12HCl(g), giving anhydrous FeCl₃ without hydrolysis.
