Question

Select the related word(s) from the given alternatives:
Kidneys : Nephron :: Central Nervous System : ___}

• A. Cerebrum
• B. Brain
• C. Neurons
• D. Spinal cord

Hint:

In biology-based analogies, look for \textbf{functional units} (e.g., nephron, neuron, alveoli).

Answer 1

The Correct Option is C

Concept: This analogy is based on the relationship between an organ/system and its basic structural or functional unit. Step 1:Understand the given relation.
\[ \text{Kidneys} \rightarrow \text{Nephron} \] A nephron is the functional unit of the kidney responsible for filtration and urine formation.
Step 2:Apply the same logic.
\[ \text{Central Nervous System} \rightarrow ? \] The basic functional unit of the nervous system is the neuron, which transmits nerve impulses.
Step 3:Evaluate the options.

• (A) Cerebrum → A major part of the brain
• (B) Brain → Entire organ
• (C) Neurons → Correct, functional units of CNS
• (D) Spinal cord → Part of CNS

Step 4:Final analogy.
\[ \text{Kidneys : Nephron :: CNS : Neurons} \]
Final Answer: Neurons
