• A. haploid
• B. triploid
• C. diploid
• D. polyploid

Answer: (A)

Verified step by step guidance

1. Understand the concept of ploidy: Ploidy refers to the number of sets of chromosomes in a cell. A single set of chromosomes is referred to as haploid, while two sets are diploid, three sets are triploid, and more than two sets are polyploid.
2. Recall that haploid cells are typically found in gametes (sperm and egg cells) in sexually reproducing organisms. These cells contain one complete set of chromosomes.
3. Diploid cells, on the other hand, are found in somatic (body) cells and contain two sets of chromosomes, one from each parent.
4. Triploid and polyploid cells are less common and usually occur in specific organisms or under certain conditions, such as in some plants or during abnormal cell division.
5. Based on the definition of haploid, identify that a cell with one set of chromosomes is classified as haploid. This matches the correct answer from the options provided.
