Which of the following is an NNRTI?

Explanation:
Identifying the class of antiretroviral drug: NNRTIs inhibit HIV reverse transcriptase by binding to an allosteric site, blocking its activity without needing phosphorylation or acting as a nucleotide chain terminator. This sets them apart from NRTIs, which must be phosphorylated inside the cell and terminate DNA synthesis by mimicking natural nucleotides. Nevirapine is a member of the NNRTI class, so it fits the question perfectly. The other drugs listed are NRTIs: they require cellular activation and halt elongation by acting as fake nucleotides. So, nevirapine is the best answer because it exemplifies the NNRTI mechanism, distinguishing itself from the NRTIs in the other options.
