To convert aniline into p-Nitroaniline, three steps are taken. Arrange following given steps in correct sequence.

A. N-Phenyl ethanamide is treated with HNO₃, H₂SO₄ and heated at 288 K.

B. p-Nitro acetanilide undergoes acidic or basic hydrolysis to give p-Nitroaniline.

C. Aniline is treated with acetic anhydride in pyridine.

Choose the correct answer from the options given below:

C, A, B

By protecting the –NH₂ group by acetylation reaction with acetic anhydride, the nitration reaction can be controlled, and the p-nitro derivative can be obtained as the major product.

Three steps:

Step 1: C. Aniline is treated with acetic anhydride in pyridine.

Step 2: A. N-Phenyl ethanamide is treated with HNO₃, H₂SO₄ and heated at 288 K.

Step 3: B. p-Nitro acetanilide undergoes acidic or basic hydrolysis to give p-Nitroaniline.
