Cells with two sets of chromosomes are
A
Haploid
B
Diploid
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: -In diploid cells, one set of chromosomes is inherited from the individual’s mother, while the second is inherited from the father. Humans have 46 chromosomes in each diploid cell. Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes.

Detailed explanation-3: -And what type of cells are diploid? The chromosomal diploid number in humans is 46 (i.e. 2n=46 chromosomes or 23 pairs of chromosomes). All the body cells like, blood cells, skin cells, muscle cells are diploid. Only sex cells or gametes are not diploid; sex cells are haploid.

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: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
