Step 1: Understanding the Question.
The question asks about the correct pairing of organs. We need to match organs that are functionally related.
Step 2: Analyzing the Options.
(i) Brain and Spinal Cord: These are part of the central nervous system, so they are correctly matched.
(ii) Gut and Stomach: These are part of the digestive system and are correctly matched.
(iii) Eyes and Ears: While both are sensory organs, they are not directly related in terms of function.
(iv) Kidneys and Lungs: Both are involved in excretion and maintaining homeostasis, so they are correctly matched.
Step 3: Conclusion.
The correct answer is (D) (i), (ii), and (iv), as all of these pairs are functionally related organs.
