Match List-I with List-II

List-I	List-II
(A) ’i’	(I) Permease
(B) ’z’	(II) Repressor
(C) ’y’	(III) Transacetylase
(D) ’a’	(IV) β-Galactosidase

The correct option is: (A) - (I), (B) - (II), (C) - (III), (D) - (IV).

Based on the provided matching, we can correlate the components in List-I with their corresponding designations in List-II as follows:
1. (A) ’i’ is matched with (I) Permease.
2. (B) ’z’ is matched with (II) Repressor.
3. (C) ’y’ is matched with (III) Transacetylase.
4. (D) ’a’ is matched with (IV) β-Galactosidase.

Thus, by sequentially pairing the items from List-I directly to the corresponding elements in List-II, we establish the matching pattern:
(A) → (I)
(B) → (II)
(C) → (III)
(D) → (IV)
