The correct answer is option A, haploid cell
Reason -
The final products of meiosis are sperm cells in male and eggs in female. The sperm and eggs are haploid cells . After meiosis, four haploid cell with chromosome containing one chromatid are produced. The sperm and egg cell (being final product of meiosis and haploid) have 23 chromosomes which join with opposite 23 chromosomes to form diploid cell.
