(a)
Interpretation:
Among the given terms, correct term should be matched for the portion of an enzyme where catalytic activity takes place.
(1) Active site (2) Lock-and-key model (3) Induced-fit model
Concept Introduction:
An enzyme is also a protein which has the capability to bind with the substrate (reactant molecule) by recognizing it. Enzymes have a unique three-dimensional shape which helps them in binding to the substrate. The size of an enzyme is typically larger than that of the substrate, and it contains a region known as active site within its structure. This active site is responsible for binding the substrate and thus catalyzing the given reaction.
(b)
Interpretation:
Among the given terms, the correct term should be matched for the active site that adapts to the shape of the substrate.

(c)
Interpretation:
Among the given terms, the correct term should be matched for an active site that has a rigid shape.
