Answer 1

HELLO MATE!!

Your answer is H2SO4 (SULPHURIC ACID)

AND

HCL(HYDROCHLORIC ACID)

Answer 2

Answer:

Here $\bold{\mathrm{H}_{2} \mathrm{SO}_{4}}$ is ‘amphoteric in nature’ as it can react with ‘acid’ as well as base.  

Explanation:

The meaning of amphoteric is the substance that can react with ‘acid’ as well as base. When it will react with acid, it will act as base and when it will react with base, it will act as an acid.

Whereas other two options, HCl and $\bold{\mathrm{H}_{3} \mathrm{PO}_{3}}$ are acidic in nature. Option (a) is correct here.
