List-I (Operon component):
(A). Promoter
(B). Operator
(C). Structural gene
(D). Regulatory gene
List-II (Role):
(I). Produces repressor protein
(II). Site where repressor binds
(III). Code for functional proteins
(IV). Binding site for RNA polymerase

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

Hint:

To remember:
- Promoter = RNA Polymerase binding
- Operator = Repressor binding
- Regulatory gene = Repressor synthesis
