This question is asking you to find a pair of words that have a similar relationship to the original pair "Kidney: Organ." The word "kidney" is a type of organ, so we need to find a pair of words where one word is a type of the other word.

Let's look at the options:

Option A: Rib: bone

Option B: Aorta: blood

Option C: Stomach: abdomen

Option D: Kneecap: skeleton

To determine the correct answer, we need to identify if one word in the pair is a type of the other word. In this case, the kidney is a specific type of organ, so the correct answer should have one word that is a specific type of the other word.

Looking at the options, we can see that Option A fits this relationship. The rib is a specific type of bone, just as the kidney is a specific type of organ.

Therefore, the correct answer is Option A: Rib: bone.

Remember, it is important to carefully read and understand the relationship between the words in the original pair and then compare it to the relationships in the options to find the best match.
