$B$. In eukaryotes replication of $DNA$ takes place in S-phase of the cell cycle.
$C$. A failure in cell division after $DNA$ replication results into polyploidy.
$D$. Crick pointed out that $DNA$ replicates semiconservatively but first proof for it came from the experiment of Meselson and Stahl who used $^{15}NH_{4}CI$ in E. coli.
