Answer and Explanation

The Correct Answer is C

B. Integrase Inhibitors block the integration of viral DNA into the host's DNA but do not directly inhibit the reverse transcription process.  
C. Nucleoside Reverse Transcriptase Inhibitors (NRTIs) inhibit reverse transcriptase, the enzyme responsible for converting viral RNA into DNA, thus directly targeting this crucial stage of the HIV lifecycle.  
D. Protease Inhibitors inhibit the protease enzyme involved in the maturation of the virus but do not affect the reverse transcription process.

C. Restricting fluid intake would be contraindicated as the patient is in a state of dehydration and hypotension.
