Final answer:
Dense connective tissue has the most fibers and provides strength and support to the body.
Step-by-step explanation:
The type of connective tissue that has the most fibers is d) Dense connective tissue.
Dense connective tissue is characterized by collagenous fibers that are packed together tightly, providing great strength and support to the body. It can be further classified as dense regular or dense irregular connective tissue. Dense regular connective tissue consists of parallel bundles of collagenous fibers, while dense irregular connective tissue consists of collagenous fibers interwoven into a mesh-like network.
An example of dense connective tissue is tendons, which connect muscles to bones and require strong support.
