d)phi× 174 bacteriophage
Explanation:
- The Chargaff's rule sates that DNA in cells of the organisms must follow 1:1 ratio on the basis of pyrimidine and purine bases. That is the amount of guanine must be equal to cytosine and the amount of adenine must be equal to thymine. This rule can be only applicable on the double stranded DNA.
- The bacteriophage ΦX174 is a small virus. It consists of single stranded closed circular DNA.
Thus on the basis of the above explanation this can be said that Chargaff rule cannot be applied on the genetic material of the bacteriophage ΦX174.

Option(d) is Right Answer
Explanation:
- phi× 174 bacteriophage is right answer
- An system of purified Escherichia coli have proteins and phi X174 quality A protein has been developed which explicitly replicates in vitro the viral strand of phi X174 from RF (replicative structure) I layout DNA and yields single-stranded round DNA items (RF prompts SS(c) DNA replication system)
- The plasmids conveying embeds got from phage phi X174 or G4 DNA which go long from 49 to 1175 base matches and contain the 30-nucleotide conserved grouping have been appeared to help phi X A protein-subordinate DNA amalgamation in replication system
