The correct answer is D) their saliva can stop blood from clotting.
Explanation: Leeches produce a substance in their saliva called hirudin, which is a potent anticoagulant. This means that it helps to prevent the blood from clotting, allowing for better blood flow to tissues and promoting healing in certain medical treatments, especially in reconstructive surgery and when managing blood circulation issues.
