Answer:

c. minimal media with leucine and streptomycin

Explanation:

Although F- Strain of bacteria require very minimal media due to the rate of their fertility factor but the minimal media must include at least one amino like leucine and antibiotic like streptomycin because these both are necessary for the proper replication process and indeed for the proper growth.
