Answer:
The correct answer is option (d)-"immunity to reinfection by any phage".
Explanation:
Lysogeny is one of the two cycles that comprise viral reproduction, at which the bacteriophage genetic information is introduced into the host bacterium's genome. Lysogeny could result in immunity to reinfection by the same phage, however this not happens when the reinfection takes place by any phage. When reinfection occurs by the same phage, the host bacteria acquires immunity resulting from the recognition of their particular DNA sequences. This not happens when reinfection occurs in any phage as they could have different DNA sequences.
