(C) The number of divisions $(n)$ is calculated by dividing the total time by the time taken for one division: $n = 175 / 35 = 5$.After $n$ divisions,the number of cells is given by the formula $N = N_0 \times 2^n$,where $N_0$ is the initial concentration.Given $N_0 = 10^5$ cells $/ ml$ and $n = 5$,the final concentration $N = 10^5 \times 2^5$.Since $2^5 = 32$,the final concentration $N = 10^5 \times 32 = 32 \times 10^5$ cells $/ ml$.

$A$: In telophase,the two daughter nuclei formed at opposite poles contain the same number of chromosomes as the parent nucleus.
$R$: In anaphase,the centromere of each chromosome splits,allowing the sister chromatids to separate.
