Which statement describes the function of muscle tissue?

• A. Attaches to bones
• B. Movement, heat, protects internal organs
• C. Walls of internal organs
• D. Detects stimuli

Answer: (B)

Muscle tissue mainly does three things: it contracts to create movement, generates heat as a byproduct of that activity, and helps protect internal organs by surrounding and supporting them. That combination—producing movement, producing heat (thermogenesis), and aiding organ protection—fits the described role of muscle tissue best.

The other statements point to where muscle tissue is located or what it can do as a broader function, not its core activities. Attaching to bones describes a typical feature of skeletal muscles but isn’t about what the tissue does overall. Walls of internal organs describes where some muscles are found (smooth muscle) rather than the action they perform. Detecting stimuli is a function of nervous tissue, not muscle tissue.
