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.$\newline$
