A diploid cell
A
has 2 sets of chromosomes
B
has more than two sets of chromosomes
C
has half the number of original chromosomes
D
cannot undergo meiosis
Explanation: 

Detailed explanation-1: -A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total. This is 22 pairs of autosomes and a pair of sex chromosomes. One copy of each chromosome pair came from the individual’s mother and the other from the individual’s father.

Detailed explanation-2: -Cells that are diploid contain two copies of each chromosome and therefore two copies of each gene. The exception to this are males who have one X and one Y chromosome. One copy of each chromosome comes from each of the individual’s parents.

Detailed explanation-3: -Diploid. A cell with two sets of chromosomes is diploid, referred to as 2n, where n is the number of sets of chromosomes. Most of the cells in a human body are diploid.

Detailed explanation-4: -The diploid chromosome number of a cell (2n) is the total number of chromosomes in a cell. In the case of humans, 2n = 46, meaning there are a total of 46 chromosomes in a diploid human cell.

Detailed explanation-5: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.
