Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. Adipose tissue.
The tissue consisting mainly of fat cells is adipose tissue. Adipose tissue plays several vital roles in the body, primarily serving as an energy reserve, storing excess energy in the form of lipids. Beyond energy storage, it also acts as an insulating layer to help regulate body temperature, provides cushioning and protection for organs, and secretes various hormones that influence metabolism and other bodily functions.
