The correct answer is:
$\begin{array}{llll}\mathrm{A} & \mathrm{B} & \mathrm{C} & \mathrm{D} \\ 1 & 2 & 4 & 3\end{array}$
Carcinogen causes cancerous tumour disjunction of chromosomes takes place in anaphase-I and II when chromosomes more to the opposite poles of the cell.
Plectonemic coiling refers to inter-twining of a double helix DNA molecule in such a way that for its correction unwinding of DNA helix molecule is required, this take place in mitosis in which sister chromatids are tightly coiled upon each other. In zygotene stage, homologs login to synapse by coming to approximate alignment.
