Solution

The correct option is C Allosteric inhibition
In allosteric inhibition, a molecule or moiety gets attached to an enzyme that alters its structure and causing a change of active sites which prevents the binding of the original substrate to enzyme and stops the reaction.
So, the correct option is 'Allosteric inhibition'.
