Solution

A substance is said to be oxidised if it either loses hydrogen or gains oxygen. A substance is said to be reduced if it either loses oxygen or gains hydrogen. In the given reaction carbon is getting oxidised to carbon dioxide and lead oxide is getting reduced to lead.
Therefore, following statements are incorrect:
(a) Lead is getting reduced
(b) Carbon dioxide is getting oxidized
