OLEGan [10]

Answer:

The answer is not in any of the options and is the following:

In a medium that has a streptomycin antibiotic it is used to kill Hfr donor cells after the conjugation is interrupted. This is entirely due to the streptomycin sensitivity allele (str-s) which are found in Hfr strains. The presence of the streptomycin resistance allele, located in the receptor, is used for the specific destruction of Hfr donor cells after conjugation occurs.
