B. The arrangement of chromosomes at metaphase of meiosis depends on the arrangement of all other chromosome pairs.

Explanation:

Each chromosome pair during meiosis arrange itself on the equator of the cell. Here, one homologous chromosome pair arranges itself on the equator independently of other homologous pairs. This random and independent arrangement of chromosomal pairs results in their random and independent segregation during anaphase.
