The two homologs of a pair move toward opposite poles of dividing cell during
(a) mitosis.
(b) meiosis i.
(c) meiosis ii.
(d) fertilization.

B, Meiosis I

Explanation:

During meiosis I, genetic material halves, and you get 2 haploid cells (n) from a diploid cell (2n). Those divide again during meiosis II to form 4 different haploid cells.

DNA replicates during interphase and starting at meiosis I, 2n homolog chromosomes attach to form n tetrads. Those tetrads align in the cellular equator during metaphase I and then separate, moving to opposite poles during anaphase I. Each cell formed receives a copy of each chromosome and then divides in a process similar to mitosis during meiosis II.
