The correct option is C Plasmid
  • Plasmid or drug resistance factor (R-factor) is a small circular DNA molecule that has autonomous replicating properties and is located in the bacterial cytoplasm.
  • It specifies the formation of sex pili and promotes conjugation between bacteria.
  • The transfer of a copy of plasmid from resistant to sensitive bacteria provides the capability of drugs resistance.
