Answer: (A)

Verified step by step guidance

1. Understand the context: The question asks for the term that describes a thin slice of tissue prepared for microscopic examination.
2. Recall definitions: A 'section' refers to a thin slice of tissue cut from a specimen, typically using a microtome, and placed on a microscope slide for viewing.
3. Differentiate from other terms: A 'stain' is a dye used to color cells or tissues to enhance contrast; a 'fixative' is a chemical used to preserve tissue structure; a 'smear' is a sample spread thinly on a slide, often used for fluids or cells, not a thin slice of tissue.
4. Match the correct term: Since the question specifies a thin slice of tissue mounted on a slide, the term 'section' fits this description precisely.
5. Conclude that the correct answer is 'Section' based on the definitions and the preparation method described.
