Solution
The correct option is B F– gets modified into F+
Bacteria carrying the F plasmid (fertility plsamid) are designated F+ and those lacking it are designated as F−. F+ and F− cells can conjugate. When conjugation occurs, the F+ cells can act as F donors. The F plasmid DNA replicates and the newly synthesized copy of F molecule is transferred to the F− recipient. However, a copy of the plasmid always remains in the donor cell. The recipient cell, after procuring the F plasmid, gets converted into F+. The transfer of the F plasmid from F+ to F− is so rapid that the F plasmid can spread like wildfire from strain to strain throughout a bacterial population.
