I'm lederberg experiment ecology colonies grow in a sense of bacteriophage when transferred by replica plotting onto 2 plates with bacteriophage they observed some colonies resistant to bacteria phage what did the observation allow them to conclude

just answer question ---  dont need explanation

Last option has same choices

Please help a bit confused

You infect bacterial cells with an experimental, bacteriophage which consists of the T4 protein coat and T2 phage DNA any new phages produced would produced
