You have to first make some observations and then ask a question. Then you make a hypothesis (or guess) what the answer is - do the experiment to see if you're right!
Answer: C) the genes of this phage were made of DNA.
Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.
