2PbO(s)+C(s)\rightarrow 2Pb(s)+CO_{2}(g)

In the above reaction, PbO reduces to Pb and C(carbon) get oxidised to carbon dioxide.

Hence, statement (a) and (b) are correct.

Thus, option (i) is correct.

Guys, All the options are wrong!!!

 The correct answer is,

 lead oxide is getting reduced and carbon is getting oxidised. We have to mention the whole element while mentioning about site of reduction as well as oxidation. Example: If PbO+H2----->Pb+H2O

 We shouldn't just say that lead is getting reduced and hydrogen gets oxidised. We MUST say that lead "OXIDE" is getting reduced and hydrogen is getting oxidised.
