Shape- selective catalysis are those reactions that depend on:
The pore structure of catalyst.
The size of reactant and product molecules.
Both (1) and (2)
None of these.
When a particular catalytic reaction depends on the pore shape of the catalyst and also on the size of reactants and products, such type of catalysis is known as shape-selective catalysis.
Therefore, the option number (3) is correct.
