Which muscle is responsible for causing goose bumps?

  1. Arrector Pili Muscle

  2. Deltoid Muscle

  3. Flexor Muscle

  4. Trapezius Muscle

The correct answer is: Arrector Pili Muscle

The correct answer is the Arrector Pili Muscle. This tiny muscle is attached to hair follicles and is responsible for causing goosebumps. When the muscle contracts, it pulls on the hair follicle, causing the hair to stand up straight, creating the appearance of goosebumps on the skin. The other options, such as the Deltoid Muscle, Flexor Muscle, and Trapezius Muscle, are not involved in producing goosebumps.
