Answer: The correct answer is-
A haploid cell has one of each chromosome whereas a diploid cell contains two of each chromosome.
Haploid cell is the genetic state of cell that represents only one/ single set of chromosomes (depicted by n, which represents number of chromosome in one basic set) in the cell.
On the other hand, diploid cell (depicted by 2n that is two set of chromosomes) represents two basic sets of chromosome in the cell. This means that it has double the number of chromosomes of the haploid cell.
In other words, each chromosome is only present once in haploid cell but two times in case of diploid cell.
Thus, second option is the right answer.
