Is this hinting at the semi-conservative DNA replication method?

Cells were grown in culture providing them onlynutrients with radioactive nucleotides. A few ofthese cells were transferred to new nutrientconditions with only non-radioactive nucleotidesand allowed to undergo cell division thirty times.Which below is an expected result? A. None of the cells will have any radioactive DNA. B. Each of the cells will contain both radioactive DNAand non-radioactive DNA. C. One half of the cells will have all radioactive DNA, theother half of cells will have all non-radioactive DNA. D. Only a few cells will have any radioactive DNA, mostwill have entirely non-radioactive DNA. E. All of the cells will have radioactive DNA.
