## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Mitosis and ploidy levels
	**Related Topics**: Cell division, haploid cells, diploid cells, life cycles of organisms
	**Prerequisites**: Basic understanding of mitosis and ploidy.
## SOLUTION PATHWAY
**Given Information**:
	Mitosis is usually restricted to one type of cell, but some exceptions exist.
	We need to identify the typical cell type and the exception.
**Method & Steps**:
	1. **Identify the typical cell type for mitosis**: Mitosis is the equational division, which means the daughter cells have the same number of chromosomes as the parent cell. This process is most common in diploid cells which need to multiply and grow.
		Reasoning: Diploid cells are the common somatic cells that undergo mitosis for growth and repair.
		Formula/Rule: None.
	2. **Identify the exception**: In some lower plants and social insects, haploid cells can also undergo mitosis.
		Reasoning: Some organisms have a life cycle where haploid cells divide mitotically. This is not the norm, but it is a known exception.
		Key Point: The question is referring to a known exception to the general rule.
	3. **Match to the options**: Based on steps 1 and 2, A should be Diploid and B should be Haploid.
		Result: Option D is the correct match.
		Verification: Confirmed with the definition of mitosis and known exceptions.
 ## OPTION ANALYSIS
[A] :x: Incorrect. Mitosis is typically found in diploid, not haploid cells.
[B] :x: Incorrect. While haploid cells can undergo mitosis in some exceptions, it's not the typical case.
[C] :x: Incorrect. While diploid cells are often the ones undergoing mitosis, this does not account for the exception.
[D] ✓: Correct. Mitosis typically occurs in diploid cells, but can occur in haploid cells in some cases.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing mitosis with meiosis. Mitosis is for growth and repair (equational division); meiosis is for sexual reproduction (reductional division).
		2.[Error 2]: Forgetting about exceptions. While it is good to know the general rule, exceptions are important too.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember that diploid cells are the workhorses of mitosis for growth.
		2.[Memory aid]: Think of the 'd' in diploid as 'doing' the division for growth, while haploid are the exception.
