(B) Lederberg's replica plating experiment was designed to demonstrate the genetic basis of antibiotic resistance in bacteria. $1$. Initially,a bacterial colony is grown on a complete medium (master plate). $2$. $A$ velvet-covered block is used to transfer the pattern of colonies onto a new plate containing a selective medium. $3$. To isolate streptomycin-resistant strains,the replica plate must contain the antibiotic streptomycin. $4$. Only those colonies that possess the mutation for streptomycin resistance will survive and grow on the medium containing streptomycin. $5$. Therefore,a complete medium supplemented with streptomycin is used to identify these resistant strains.

In Lederberg's replica plating experiment,what should be used to obtain streptomycin-resistant strains?
