[AI-generated answer — Bot GPT 3.5]

C. 4 grams of products are produced

This can be determined by the law of conservation of mass, which states that mass is conserved in a chemical reaction. Since the total mass of the reactants (2 grams of A + 3 grams of B = 5 grams) must equal the total mass of the products, the total mass of the products produced must also be 5 grams.
