Answer:
C
Solution:
Lac operon consists of three structural gene X, Y, and A. Gene X synthesizes enzyme beta-galactosidase which breaks lactose into glucose and galactose. Gene Y synthesizes enzyme Lactose permease which increases membrane permeability for lactose. Gene A synthesizes enzyme transacetylase which degrades the galactose.
