Solution

The correct option is B Anaphase I
Anaphase I of meiosis is characterized by separation of homologous chromosomes. This leads to reduction in chromosome number to half of that present in the mother cell. Meiosis II is similar to mitosis and centromere splits during anaphase II, thus chromosome number remains the same which has been halved after meiosis I.
