The correct option is A Yellow elastin fibres
Elastin is synthesized by fibroblasts. In tissues, such as, yellow elastic tissue of ligaments and elastic connective tissue layer of the major arteries, elastin is the more important contributor to the extracellular matrix than collagen. Since, this yellow elastin is resistant to drying and the action of proteolytic enzymes, elastin has survived in good condition in Egyptian mummies and other preserved bodies.
Thus, the correct answer is option (A), 'Yellow elastin fibres'.
