Verified step by step guidance

1. Step 1: Understand the concept of special senses. Special senses are those that have specialized organs dedicated to them, such as the eyes for vision, ears for hearing, and taste buds for taste. These senses are distinct from general senses like temperature, pain, and touch, which are detected by receptors distributed throughout the body.
2. Step 2: Review the list of options provided in the problem: Temperature, Pain, Touch, and Vision. Identify which of these has a specialized organ associated with it.
3. Step 3: Recall that temperature, pain, and touch are general senses. They are detected by free nerve endings or other receptors located in the skin and tissues, but they do not have specialized organs.
4. Step 4: Recognize that vision is a special sense because it is associated with a specialized organ—the eyes. The eyes contain photoreceptors (rods and cones) that detect light and allow for the perception of vision.
5. Step 5: Conclude that the correct answer is Vision, as it fits the definition of a special sense due to its reliance on a specialized organ (the eyes).
