• C. DNA
• D. Protein

Answer: (C)

Verified step by step guidance

1. Understand that in genetics, a gene is defined as a unit of heredity responsible for passing traits from parents to offspring.
2. Recognize that a gene is a specific segment of a larger molecule that contains the instructions for making functional products.
3. Recall that the molecule containing genes is DNA (deoxyribonucleic acid), which stores genetic information.
4. Know that the functional products produced from genes are typically proteins or RNA molecules, but the gene itself is a segment of DNA.
5. Therefore, the correct description is that a gene is a segment of DNA that produces a functional product.
