The correct answer is A. Exteroceptors.
Exteroceptors are sensory receptors that detect stimuli from the external environment. They are located in the skin, eyes, ears, nose, and tongue. Pressure, pain, and temperature receptors are all exteroceptors.
Proprioceptors are sensory receptors that detect stimuli from within the body. They are located in muscles, tendons, and joints. Proprioceptors provide information about body position and movement.
Interoceptors are sensory receptors that detect stimuli from the internal organs. They are located in the heart, lungs, stomach, and intestines. Interoceptors provide information about the state of the internal organs.
Mechanoreceptors are sensory receptors that detect mechanical stimuli, such as pressure, touch, and vibration. They are located in the skin, muscles, tendons, joints, and inner ear. Mechanoreceptors are responsible for our sense of touch.
