Which of the following is an example of connective tissue?

Connective tissue plays a vital role in providing support, structure, and cohesion to other tissues and organs in the body. Cartilage is a specific type of connective tissue characterized by its semi-rigid structure, which allows it to provide flexibility and support in various areas such as joints, the ear, and the nose. It helps reduce friction between bones and serves as a cushion, which illustrates the functions of connective tissue in maintaining structural integrity and facilitating movement.

In contrast, muscle tissue is responsible for movement and contraction, epithelial tissue covers and protects surfaces, and nervous tissue is involved in communication and signaling within the body. These types of tissues serve distinct functions that do not align with the primary roles of connective tissue, further emphasizing why cartilage is correctly identified as an example of connective tissue.
