Select the percentage in which these amine derivatives are formed in the reaction mixture along with the reason for the nitration of aniline:

• A
  $I \to 2\%, II \to 47\%, III \to 51\%$. In the acidic medium,aniline is protonated to form the anilinium ion which is ortho directing.
• B
  $I \to 51\%, II \to 2\%, III \to 47\%$. In the acidic medium,aniline is protonated to form the anilinium ion which is para directing.
• C
  $I \to 51\%, II \to 47\%, III \to 2\%$. In the acidic medium,aniline is protonated to form the anilinium ion which is meta directing.
• D
  $I \to 50\%, II \to 20\%, III \to 20\%$. In acidic medium aniline is protonated to form the anilinium ion which is ortho directing.
