Solution

The correct option is A Anaphase II
Prophase I of meiosis I is marked by synapsis of homologous chromosomes and crossing over. Metaphase I is marked by movement of pairs of homologous chromosomes towards equator and their arrangement on it. Condensation of chromatin and appearance of chromosomes with sister chromatids takes place during prophase II. Metaphase II is marked by 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.
