Explanation:

1. Analyze each option:

• "It transports nutrients in the body": Lymph helps in transporting nutrients (like fats absorbed from the digestive tract) and also removes waste, so this is correct.
• "It produces hormones in the body": Hormones are produced by endocrine glands, not lymph, so this is incorrect.
• "It synthesizes antigens in the body": Antigens are foreign substances or produced by pathogens, lymph doesn't synthesize them, so this is incorrect.
• "It circulates macrophages in the body": Lymphatic system carries immune cells like macrophages to fight infections, so this is correct.
