C Correct answer
Explanation

Pristinamycin belongs to the streptogramin family. It is used to treat VRE (vancomycin resistant enterococci) infections. It is effective against VRE because it inhibits protein synthesis and vancomycin acts on the cell wall. Thus, its mechanism of action is altogether different than vancomycin. It also enters the bacterial cell easily, whereas other protein inhibitors fail to do so.
