Question

Match List-I with List-II
{|p{7cm}|p{7cm}|} List-I (Column A) & List-II (Column B)
(A) n-hexadecanaic acid & (I) Watson and Crick
(B) Secondary amino group & (II) Proline
(C) Double helical DNA & (III) Palmitic acid
(D) Enantiomer & (IV) Optical isomer

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (II), (C) - (I), (D) - (IV)

Hint:

Remembering that Proline is the only standard amino acid with a secondary amine (imino) group helps you quickly match (B) with (II).
This immediately narrows down the options in similar biochemical matching questions.
