Step 1: Understanding the Concept:
The question asks for the scientific term for the sense that allows us to know where our body parts are and how they are moving, even without looking at them.
Step 2: Detailed Explanation:
(A) Kinesthetic sense (or Kinesthesia): This is the sense that detects bodily position, weight, and the movement of the muscles, tendons, and joints. It allows you to touch your nose with your finger even with your eyes closed. This directly matches the description.
(B) Skin senses: These are the senses of touch, pressure, temperature, and pain, processed through receptors in the skin.
(C) Vestibular senses: This sense, located in the inner ear, is primarily responsible for balance, orientation, and sensing the movement of the head in space. While related to body position, it is more about equilibrium than the position of individual limbs.
(D) Olfactory sense: This is the sense of smell.
Step 3: Final Answer:
The kinesthetic sense is the sense of movement and the position of our body parts.
