Solution

Verified by GMS

Correct option is A)

As X reacts with Acid, it's a metal hence X is an electropositive element. Hence (I) is correct.
X reacts with a base as well.
There are some metals, like Zn and Al, that react with bases too.
Oxides of such metals are amphoteric, which means they can react with both acids and bases.
These oxides are basic as well as acidic in nature.
Hence, (II) and (III) are also correct.
As no such electronegative element, non-metal shows these properties.
Hence (IV) is incorrect.
