How it converts?

I do not agree.

In the soil ammonia gets oxidised to nitrates and bthen to nitrites. Plants takes up this nitrites which are reconverted to ammonia in the surface of leaves. And the excess nitrites present in the soil gets reduced to free nitrogen.

Nodulated roots having nitrogen fixing bacteria to convert nitrates into free nitrogen.

It is separated with the process called ammonification.

But ultimately it convert in to protien.

It is so converted by the nitrogen fixing bacteria i.e.rhizobium process nitrification.

When a plant process photosynthesis, last products are O2, glucose, also it gives a free N2.

Because plant don't give us 100% O2 it also consist some part of N2, CO2.

Therefore last product is N2, answer A is correct.

To maintain level of nitrogen in atmosphere, plants do various processes. This process of maintaining level of nitrogen is called nitrogen cycle.

I do not agree I think the nitrates is used by the plant for synthesis of protein after which a bacterium in the soil called Planococcus reduces it to to atmospheric nitrogen.
