Please answer Q26 and tell why the other options are incorrect.

Dear Student,
An alloy is a homogenous mixture of two or more metals or non-metals or nonmetals mixed in a molten state. It can either be a solid solution of the elements of a single-phase or a mixture of two or more metallic phases.
Hence Carbon and Sulphur cannot be the correct options since they are non-metals.
Both Copper and Zinc are metals hence they form basic oxide.
Since Copper is below Zinc in the reactivity series
So the metal E is Copper.
Option A is Correct
