The "Bronsted acid" is the proton donor....

Explanation:

And as written....

NO_2^(-) + H_2O(l) rightleftharpoons HNO_2(aq) + HO^-

....the "water molecule" is the "Bronsted acid", "the proton donor...."

Do you agree?

Which is the "Bronsted base"?

In the reaction between NO_2^(-) and water, which species is the acid?

Explanation:

The Bronted acid always donates a proton.

underbrace(NO_2^(-))_"conjugate base" +H_2O -> underbrace(HNO_2)_"parent acid" + OH^-

In this case, water donates a hydrogen to NO_2 to make HNO_2. Water then becomes OH^- since it lost one hydrogen.
