The existence of a single set of chromosomes in an organism's cells is referred to as haploidy. Diploid creatures (two sets of chromosomes, one from each parent) reproduce sexually. Only the egg and sperm cells in humans are haploid. Hence option 4 is correct.

A diploid cell is one that has two copies of each chromosome. As a result, a Zygote is diploid. Almost every human body cell contains two homologous, or comparable, copies of each chromosome. The zygote is diploid (has two sets of chromosomes) because to the presence of both of its parents' genes. Hence option 1 is incorrect.

Sperm is not the only haploid cell mentioned in the options. Hence option 2 is incorrect.

Ovum is not the only haploid cell mentioned in the options. Hence option 3 is incorrect.
