Which element is oxidized in the reaction below? fe(co)5 (l) + 2hi (g) → fe(co)4i2 (s) + co (g) + h2 (g) a. c?

The element which is oxidized  in  the  reaction below 
that is

Fe(Co)5  (l) +  2 Hi (g)=  Fe (CO)4 i2(s) +Co (g)+H2 (g)  is

 Fe   this is because   fe in Fe(CO)5  compound move from oxidation state  of  Positive five (5^+)  to  oxidation  state  of  positive  six ( 6^+)  in Fe(CO)4i2  compound.   fe  is  oxidized  by Hi  while  Hi  itself is  reduced  by   Fe,therefore Fe  act as a  reducing agent
