When a cell contains two sets of chromosomes it is said to be
A
haploid
B
diploid
C
bichromosomal
D
double haploid
Explanation: 

Detailed explanation-1: -Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism’s cells, with each parent contributing a chromosome to each pair. Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs.

Detailed explanation-2: -A diploid cell is a cell that contains two sets of chromosomes. This is double the haploid chromosome number (n). So the correct option is “2n".

Detailed explanation-3: -In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.

Detailed explanation-4: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females.

Detailed explanation-5: -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.
