Which series of reactions correctly represents chemical relations related to iron and its compound ?

Option: 1

Fe \xrightarrow[]{dil H_{2}SO_{4}}FeSO_{4}\xrightarrow[]{ H_{2}SO_{4},O_{2}}Fe_{2}\left ( SO_{4} \right )_{3}\xrightarrow[]{heat}Fe


Option: 2

Fe \xrightarrow[]{O_{2},heat}FeO\xrightarrow[]{ dil H_{2}SO_{4}}FeSO_{4}\xrightarrow[]{heat}Fe


Option: 3

Fe \xrightarrow[]{Cl_{2},heat}FeCl_{3}\xrightarrow[]{ heat ,air}FeCl_{2}\xrightarrow[]{Zn}Fe


Option: 4

Fe \xrightarrow[]{O_{2},heat}Fe_{3}O_{4}\xrightarrow[]{ CO ,600^{\circ}C}FeO\xrightarrow[]{CO ,700^{\circ}C}Fe

As learnt 

Fe_{2}(SO_{4})_{3} cannot convert to Fe on heating, instead oxide will be formed.

FeCl_{3} cannot be reduced by heating in air.

Fe_{2}SO_{4} cannot be coverted to Fe on heating, oxide will be formed

Fe\overset{O_{2}, heat}{\rightarrow}Fe_{3}O_{4}\overset{CO, 600^{\circ}C}{\rightarrow}FeO \overset{CO, 700^{\circ}C}{\rightarrow}Fe
