Which statement about spaying is supported by the material?

• A. Sterilization does not change temperament
• B. Weight and sterilization are connected
• C. Spaying decreases risk of cancer & infection
• D. Spay makes dogs hyperactive

Answer: (C)

Spaying changes the dog’s hormonal balance by removing the ovaries and uterus, which lowers the activity of reproductive tissues. Because of this, the risk of cancers in reproductive tissues and the risk of a serious uterine infection (pyometra) are reduced or eliminated. This directly matches the idea that spaying lowers cancer and infection risk, making that statement the best fit for the material. Other points—such as temperament staying the same, weight changes after sterilization, or claims of hyperactivity—are less central to the health risk reduction discussed and aren’t universally true, so they don’t carry the same clear support.
