The Correct Option is B

Approach Solution - 1

Dense irregular connective tissue contains collagen fibers arranged in multiple directions. It provides strength and flexibility to tissues that are subjected to stretching in various directions.
It is typically found in:
- The deeper layer of the dermis (reticular layer) of the skin
- Submucosa of the digestive tract
- Periosteum and perichondrium
Other options:
- Umbilical cord contains Wharton's jelly (mucous connective tissue).
- Vocal cords have dense regular elastic tissue.
- Epiglottis contains elastic cartilage, not connective tissue.

Approach Solution -2

Dense irregular connective tissue occurs in:

Dense irregular connective tissue is a type of connective tissue characterized by densely packed collagen fibers that are arranged in an irregular or random pattern. Unlike dense regular connective tissue (like tendons and ligaments), where fibers run parallel, dense irregular connective tissue fibers run in multiple directions. This structural arrangement allows it to withstand tension and mechanical stress from various directions, making it ideal for protective and supportive roles in the body.

One of the most prominent locations where dense irregular connective tissue is found is in the deeper layer of the dermis of the skin (also known as the reticular layer). In this region, the tissue provides the skin with both strength and elasticity, enabling it to resist tearing from stretching forces applied in different directions. This tissue is also found in the fibrous capsules of organs and joints, where similar multidirectional strength is required.

Therefore, its presence in the deeper region of the dermis of the skin is essential for maintaining the skin’s integrity under mechanical stress.

Correct Answer: Deeper region of dermis of skin
