Solution

The correct option is B Anaphase-I
During Anaphase I of meiosis I homologous pairs of chromosomes are separated and pulled to opposite ends. This results in each end having a single set of chromosomes (genome). This does not follow maternal paternal segregation. The segregation and assortment is random. Only thing ensured here is each side has one complete set. example, 23 chromosomes in humans.
So, the correct answer is 'Anaphase-I'
