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 organ/system and its functional unit. Step 1:Understand the given pair: \[ \text{Kidneys} \rightarrow \text{Nephron} \] Nephron is the functional unit of the kidney.
Step 2:Apply the same relation: \[ \text{Central Nervous System} \rightarrow ? \] The functional unit of the nervous system is the neuron.
Step 3:Analyze options:

• (A) Cerebrum → Part of brain
• (B) Brain → Organ
• (C) Neurons → Correct; functional units
• (D) Spinal cord → Part of CNS

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