C. A-IV, B-II, C-I, D-III
Step-by-step solution
According to the catalytic cycle of an enzyme action described in NCERT: First, the substrate binds to the active site of the enzyme, fitting into the active site (A-IV). The binding of the substrate induces the enzyme to alter its shape, fitting more tightly around the substrate, which is known as induced fit (B-II). The active site of the enzyme, now in close proximity to the substrate, breaks the chemical bonds of the substrate to form the enzyme-product complex (C-I). Finally, the enzyme releases the products,
