Explanation / Answer

1.

H2CO3 can donate two protons. Subtance that can donate two protons is called diprotic acid.

A diprotic acid can donates two protons.

A binary acid is the one which is formed by combination of H and non-metal and has general formula HX.

An amphiprotic molecules means it can donate proton as well accets proton.

Bronsted-Lowry base is the one which accepts protons.

So, the best discription of the image is A) A diprotic acid.
