Analyze the question prompt

The question asks for the biological process where unspecialized cells transform into specialized cells (like neurons or epithelial cells).

Define the biological terms

• Differentiation: The process by which unspecialized cells (like stem cells) become specialized in structure and function.
• Division: The process of cell reproduction (mitosis/meiosis) to make more cells.
• Proliferation: An increase in cell number through rapid cell division.

Connect to prenatal development

During Human Prenatal Development, stem cells undergo division and then specialize into distinct cell lineages to form tissues.

Evaluate the options

• Option (a) "Differentiation" directly matches the definition of becoming specialized.
• Option (b) and (c) refer to increasing cell numbers, not specialization.
• Option (d) is incorrect because (a) is correct.
