four cells, each with the same number of chomosomes as the parent cell.
C
two cells, each with the same number of chomosomes as the parent cell.
D
four cells, each with half as many chomosomes as the parent cell.
E

Explanation: 

Detailed explanation-1: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Detailed explanation-2: -Meiosis results in reduction of chromosome number to half. Hence, if daughter cells have 4 chromosome, the original parent or mother cell must have 8 chromosomes.

Detailed explanation-3: -These pairs break apart and get separated in meiosis I. Thus, each of the two daughter cells formed after first meiotic division have half the number of chromosomes, i.e., 23. Now each of the 23 chromosomes have two identical chromatids. So, in meiosis II, these chromatids get separate and in total 4 cells result.
