$Fe \overset{dil. H_{2} {SO}_{4}}{⟶} {FeSO}_{4} \overset{H_{2} {SO}_{4}, O_{2}}{⟶} {Fe}_{2} {({SO}_{4})}_{3}$ $\overset{Δ}{⟶} Fe$

$Fe \overset{O_{2}, heat}{⟶} {Fe}_{3} O_{4} \overset{CO, 600^{\circ} C}{⟶} FeO$

$\to CO, 700^{\circ} C \to Fe$

$Fe \overset{{Cl}_{2}, heat}{⟶} {FeCl}_{3} \overset{heat, air}{⟶} {FeCl}_{2} \overset{Zn}{⟶} Fe$

$Fe \overset{O_{2}, heat}{⟶} FeO \overset{dil. H_{2} {SO}_{4}}{⟶} {FeSO}_{4} \overset{Δ}{⟶} Fe$

answer is B.

Detailed Solution

When heated in air, ${FeCl}_{3}$ cannot be reduced according to equation 1.
In equation 3, heating will not cause ${Fe}_{2} {({SO}_{4})}_{3}$ to convert to $Fe$ ; instead, oxide(s) will develop.
In equation 4, heating does not convert ${FeSO}_{4}$ to $Fe$ ; instead, oxide(s) develop.
