Solution

The correct option is A 23, 2C
The typical human cell has 46 chromosomes and only 1C since DNA has not replicated.
After meiosis I, the cells each have 23 chromosomes and 2C since the chromosomes are tetrads or duplicated chromosomes.
At the metaphase I, the dividing cell still has 23 chromosomes and 2C since there is no replication of chromosomes between meiosis I and II.
