Final answer:
The true statement about dense connective tissue is that it includes a great deal of collagen, making it resistant to stretching and providing tensile strength.
Step-by-step explanation:
The true statement is: B) Dense connective tissue includes a great deal of collagen. Dense connective tissue, characterized by its high content of collagen fibers, offers enhanced tensile strength and resistance to stretching. There are two types: dense regular connective tissue, where fibers are parallel to each other as found in ligaments and tendons; and dense irregular connective tissue, with fibers interwoven into a mesh-like network, such as in the dermis of the skin.
Contrary to one of the options presented, dense connective tissue does not primarily consist of reticular fibers. Moreover, loose connective tissue does contain collagen fibers but they are not as densely packed as in dense connective tissue, and cartilage, while it is a type of connective tissue, falls under the category of supportive tissue rather than loose connective tissue.
