These protein fibers are stronger than steel of the same diameter. They are flexible and resistant to stretching.
A
collagen fibers
B
reticular fibers
C
elastic fibers
D
ground substance
Explanation: 

Detailed explanation-1: -Collagen fibres are the most widespread and made up of fibrous protein, collagen. Collagen fibres are flexible and have high tensile strength (comparable to steel). Elastic fibres form a network and can be stretched like a rubber band. They are made up of protein elastin.

Detailed explanation-2: -Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the movement of the body.

Detailed explanation-3: -All connective tissues contain protein fibers. The most common fiber type is made of the protein collagen; collagen fibers are flexible and strong.

Detailed explanation-4: -Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress. More than 99 percent of the body’s calcium is contained in the bones and teeth.
