The correct option is 3.
Polyploid cells and organisms are those containing more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (Eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent. However, polyploidy is found in some organisms and is especially common in plants. In addition, polyploidy also occurs in some tissues of animals that are otherwise diploid, such as human muscle tissues. This is known as endopolyploidy. Species whose cells do not have nuclei (Prokaryotes) are haploid organisms, with only a single chromosome in each cell. Most eukaryotes have diploid cells, but produce haploid gametes (eggs and sperm) by meiosis. In plants and multicellular algae the gametophyte generation is haploid, and produces gametes by mitosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Male bees and other Hymenoptera, for example, are monoploid.
