The correct answer is option B) The enzyme has active sites where the substrate binds with the enzyme to form a complex.

The active site of the enzyme is the location, where the substrate bind to it. The binding of the substrate with the enzyme result in the formation of the enzyme substrate complex. After this, the substrate is converted into the products. The lactose is a disaccharide, which have glucose and the galactose monomer. Lactase is an enzyme, which help in the lysis of the lactose in glucose and galactose.

B) The enzyme has active sites where the substrate binds with the enzyme to form a complex. When the substrate binds to the active site, an induced fit is formed where the enzyme changes its shape in order to better serve the substrate and lower the activation energy of the reaction.
