First, let’s restate the problem in our own words and list the given options to keep the details clear.
Question: A diploid cell with 2n = 16 undergoes mitosis and cytokinesis. What is the result?
Answer options:
1) 2 cells; each with 2n = 8
2) 4 cells; each with 2n = 32
3) 2 cells; each with 2n = 32
4) 2 cells; each with 2n = 16
5) 4 cells; each with n = 8

Now, evaluate each choice:
Option 1: 2 cells; each with 2n = 8. This would imply a reduction in chromosome number from 16 to 8, which is not what happens in mitosis. Chromosome number is maintained during mitosis and cytokinesis; only meiosis produces haploid cells. Therefore, this option is incorrect.
Option 2: 4 cells; each with 2n = 32. This suggests an increase in chromosome number and an increase in cell count beyond the standard mitotic process. Neither happens in ordinary mitosis: you don’t double the DNA content to 32, nor do you produce four cells. So this is incorrect.
Option 3: 2 cells; each with 2n = 32. Here, there is an incorrect chromosome count (32 instead of 16) and the cell count is wrong for a typical mitosis event. Mitosis yields two genetically identical diploid daughter cells with the same chromosome number as the parent, not a higher count. This option is incorrect.
Option 4: 2 cells; each with 2n = 16. This aligns with the core principle of mitosis: the chromosome number is preserved, and the cell divides to form two daughter cells. Each daughter cell remains diploid with the same 2n value as the original (16). This is the correct interpretation.
Option 5: 4 cells; each with n = 8. This resembles what would happen after meiosis I and II or in a situation of complete cytokinesis with a haploid outcome, but not after mitosis in a diploid cell. Since the starting material is 2n = 16 and the process specified is mitosis and cytokinesis, producing four haploid cells is incorrect.

In summary, the only option that faithfully reflects mitosis preserving the chromosome number and yielding two diploid daughter cells is Option 4: 2 cells; each with 2n = 16. The other options either misstate the chromosome number, the ploidy, or the number of daughter cells, contradicting the fundamental mitotic outcome.
