Solution

The correct option is A Anaphase I
The prophase I of meiosis I is marked by synapsis of homologous chromosomes and crossing over. Metaphase I is marked by the movement of pairs of homologous chromosomes towards the equator and their arrangement on it. Anaphase I is marked by separation of homologous chromosomes and their movement towards opposite poles. The condensation of chromatin and appearance of chromosomes with sister chromatids takes place during prophase II. Metaphase II is marked by the arrangement of chromosomes (each with two sister chromatids) on cell's equator which is then separated by splitting of centromere and move towards opposite poles during anaphase II.
Therefore, the correct answer is option A.
