Answer 2

Answer:

contributing

Explanation:

This sentence is in present continuous tense.

As helping verb am is used after the subject in the given sentence, so we should use 'ing' form or present participle form of verb after the helping verb.

So the sentence should be,

I am contributing to my nation's infrastructure.

The structure of the sentence in present continuous tense is -

Subject + am/is/are + verb + ing + object + complement.

Example -She is going to Market.
