first of all the answer given at the back is right!
now the explanation:
the equation for Iodine is : 2I- - 2e- ---> I2
now as u can see the iodine is losing electrons and is thus oxidised(oil rig)
Whenever a substance is oxidised, it acts as a reducing agent
reason: because it is losing the electrons, which will later be gained by Cl to be reduced, therefore it is aiding Chlorine in getting reduced.
Do u get what i am trying to say?
Basically, always remember that whichever ion gets reduced acts as the oxidising agent and whichever gets oxidised acts as a reducing agent.
Tell me if you still didn't understand

Hey aditoxic!
Thanks alottt dude. I'm clear wid the ans nw. This concept of oxidation n reduction is tooo confusin for me but nw i hav got it.
once agn Thanks alot :)
@d!_†oX!©:
ur welcome dude!!
Saladin:
TO AADI
Oxidation is loss of electrons
Reduction is gain.
An oxidising agent will gain electrons in the process
A reducing agen will lose electron in the process
So scandium has the lowest number of electrons, so it will be more prone to lose them. Thus best reducing agent.
Mercury needs one more electron to make full shell, so will be more prone to gain electrons. Thus best oxidising agent.

out of Scandium, Iron, Tin, and Mercury
why is Mercury the best oxidising agent agent and Scandium the best reducing agent?>?>?
--- End quote ---
mercury is least reactive nd scandium the most!!
so whenever scandium reacts it reduces the others!!
and also when mercury reacts it takes up oxygel
like mercuryoxide+Mg=MErcury+MgO2!!!
samjha!!
@d!_†oX!©:
thanks dude....and thanks shrey...samajh gaya!!!
By the way dude...its adi for adi_toxic not aadi...dts the other one
