which diagram correctly shows a cell undergoing meiotic cell division?

Explanation:

Meiotic cell division starts with a diploid cell (46 chromosomes in humans) and results in four haploid cells (23 chromosomes each). Diagram W shows mitosis (diploid to diploid). Diagram Y has incorrect ploidy labels (haploid starting cell is wrong for meiosis in this context). Diagram Z has incorrect chromosome number in the end - stage (should be haploid with 23, not 46). Diagram X starts with a diploid cell (46 chromosomes) and forms four haploid cells (23 chromosomes each), which is characteristic of meiosis.

Answer:

X
