(B) In recombinant $DNA$ technology,$X-gal$ ($5$-bromo$-4-$chloro$-3-$indolyl-$\beta$-$D$-galactopyranoside) is a chromogenic substrate used to detect the activity of the enzyme $\beta$-galactosidase.When the enzyme $\beta$-galactosidase is present and active,it cleaves the $X-gal$ molecule.This cleavage results in the formation of an insoluble blue-colored product.This process is commonly used in blue-white screening to identify recombinant colonies in cloning experiments.

What color does $X-gal$ produce in the presence of $\beta$-galactosidase?
