Explanation

To solve this problem, we need to match the genes of the Lac operon with their respective products. Let's analyze each gene: $\newline \bullet$ a. i gene: $\newline$ - The i gene codes for the repressor protein, which binds to the operator region to inhibit transcription. $\newline$ - This matches with (i) Repressor. $\newline \bullet$ b. z gene: $\newline$ - The z gene codes for β-galactosidase, an enzyme that breaks down lactose into glucose and galactose. $\newline$
