In connective tissue, the role of elastic fibers is to .
A. retain fluid
B. provide flexibility
C. form delicate networks around blood vessels.
D. provide tensile strength

The correct answer is B. provide flexibility

Explanation:

Elastic fibers are made up of majorly of a protein called elastin. This protein provides the property to elastic fiber to stretch and contract and come to its original shape. Therefore elastic fiber plays an important role in providing flexibility in connective tissue.

Bigger arteries have a large amount of these elastic fibers because they continuously contract and relax during systole and diastole of the heart. Tendon and ligament have flexibility because it is made up of connective tissue which has elastic fibers. So the correct answer is B.
