Oxacillin
Erythromycin
Clindamycin
Vancomycin
Linezolid.
Correct Answer : A,B,C

Choice B is wrong becauseAbacavir is wrong because it is anucleoside reverse transcriptase inhibitor (NRTI)that inhibits the enzyme reverse transcriptase, which converts viral RNA into DNA.
It does not prevent viral fusion with host cell membrane.
Choice C is wrong becauseDarunavir is wrong because it is aprotease inhibitor (PI)that inhibits the enzyme protease, which cleaves viral proteins into functional units.
It does not prevent viral fusion with host cell membrane.
Choice D is wrong becauseFosamprenavir is wrong because it is also aprotease inhibitor (PI)that inhibits the enzyme protease.
