Answer:
The correct answer would be C. ³⁵S has more neutrons than ³²S; Hershey and Chase used it because it is radioactive and can be easily traced.
Sulfur-35 (³⁵S) is one of the isotopes of the sulfur which has 16 protons (same as sulfur-32) but 19 neutrons as compared to the 16 neutrons of sulfur-32.
It is a radioactive isotope which breaks down by beta-decay and gets converted into ³⁵Cl.
They used ³⁵S for radioactive labeling of the protein coat of the bacteriophage. It helped them to trace the movement or transfer of protein efficiently.
