The correct answer is d) dense irregular connective tissue.
The reticular layer is the deeper and thicker part of the dermis, which lies beneath the papillary layer. This layer provides strength and elasticity to the skin, allowing it to withstand stress from various directions. Dense irregular connective tissue is characterized by a network of collagen fibers that are irregularly arranged, providing structural support and helping to resist tearing and stretching.
In contrast, the other options represent different types of connective tissues. Hyaline cartilage is mainly found in areas like the respiratory tract and joints; loose connective tissue is more flexible and found in areas that require elasticity; and dense regular connective tissue has fibers that are arranged in a parallel pattern, which is more typical in tendons and ligaments. Therefore, the composition of the reticular layer specifically calls for the durability and multi-directional support provided by dense irregular connective tissue.
