Answer: Option A
Step-by-step explanation:
The drug AZT belongs to the group of drugs that is used in case of HIV. These class of drugs are known as Nucleoside analogues.
This drug interferes with the enzyme reverse trsncriptase which is used by the cells affected from HIV for the production of new viruses.

Hence, the correct answer is option A
