Answer

Explanation:

Step1: Count atoms in carbonic acid

For $H_2CO_3$, number of atoms = 2 (H) + 1 (C) + 3 (O) = 6.

Step2: Count atoms in nitric acid

For $HNO_3$, number of atoms = 1 (H) + 1 (N) + 3 (O) = 5.

Step3: Count atoms in phosphoric acid

For $H_3PO_4$, number of atoms = 3 (H) + 1 (P) + 4 (O) = 8.

Step4: Count atoms in sulfuric acid

For $H_2SO_4$, number of atoms = 2 (H) + 1 (S) + 4 (O) = 7.

Answer:

C. Phosphoric acid
