Answer:

#"Option B"#

Explanation:

Formally, reduction is the GAIN of electrons, and a net DECREASE in oxidation number........

Dichlorine oxidizes the #Fe(II)# centre to #Fe(III)#, but is itself REDUCED in the process, as it is conceived to accept electrons from the iron centre.

#stackrel(0)Cl_2+2e^(-)rarr2stackrel(-I)Cl#

The zerovalent element is reduced to the univalent anion.........
