Option c is correct. Because, if the pore is small, diffusion occurs and the rate of reaction is slow.
Option B is incorrect just the statement is vice-versa. When the pore is large, the reaction don’t go through diffusion. So the rate of reaction is fast. But the product obtained may be not desired one. Because it may not come in contact properly with the catalyst.
And hence its activated sites are not decreased. So product obtain may not be the desired one.

Here the diffusional effect are likely to affect the rate of reaction so the rate-controlling step will pore diffusion which means fast reaction and thus fast reaction with small pore size.
So, The answer is option A.
So, The answer is option A.
