d. cannot be determined

If a cell has 18 chromosomes the daughter cells would have 18 chromosomes after mitosis.

c. 18

Explanation:

Mitosis is the DNA replication process which maintains the number of chromosomes in daughter cells equal to number of chromosomes in parent cell. In the process the parent cell divides into two daughter cells having the same chromosome number as that of parent cell.

Meiosis is a process different from that of mitosis where each parent cell divides into four daughter cells having half the number of chromosomes present in the parent cell.

Since sex cells have to be haploid in organisms like human beings, it is the process of meiosis that takes place in reproductive cells.
