Which statement best describes the major role of the reproductive system?

• A. It controls the body's immune response.
• B. It manufactures, transmits, and maintains the cells and environment necessary for reproduction.
• C. It regulates digestion.
• D. It stores minerals.

Answer: (B)

The major role of the reproductive system is to produce sex cells, move them to where fertilization can occur, and maintain the environment needed for reproduction and, if pregnancy happens, support development. The statement that describes manufacturing, transmitting, and maintaining the cells and environment for reproduction captures this whole process: the gonads make gametes (sperm and eggs), the ducts and glands transport them, and the tissues (like the uterus and related secretions) provide the conditions for fertilization and, if needed, pregnancy. The other options refer to functions of other body systems—immune defense, digestion, and mineral storage—so they don’t describe the reproductive system’s main purpose.
