Answer»

Correct answer is (d) The cleaving of the carrier is also site-specific

To explain I would say: The LIMITATION of the prodrug designing is the formation of unexpected metabolite, the inert carrier can be cleaved off forming a toxic molecule, and prodrug might CONSUME vital nutrients. If the carrier cleavage is site specific it is an advantage.
