Solution

Elastic fibres are composed of the protein collagen.

Explanation:

Elastic fibres are not made of collagen. Instead, they consist primarily of the protein elastin, which provides elasticity and resilience to tissues. Collagen fibers, on the other hand, provide tensile strength and are a different structural protein found in connective tissues. The other statements are true: macrophages are vital for defense, fibroblasts produce connective tissue fibres, and mast cells produce histamine.
