Choose the word which is least like the other words in the group:

Appeared in: DSSSB 6 September 2024

Explanation

The Ear is the correct choice as it is functionally and structurally different from the other options.
The Liver, Pancreas, and Kidney are all internal visceral organs involved in metabolic, digestive, and excretory functions.
The Ear is a complex sensory organ responsible for the senses of hearing and balance, and it is located externally.
This distinction in classification (sensory vs. internal visceral) makes the Ear the outlier in the group.

Option A: The Liver is an internal organ, similar to the Pancreas and Kidney, involved in vital metabolic and digestive processes. It fits within the group of internal visceral organs.
Option B: The Pancreas is an internal organ that functions in both the digestive and endocrine systems, similar to the Liver and Kidney in being a visceral organ. It does not stand out from the group.
Option C: The Kidney is an internal organ of the urinary system, responsible for filtration and excretion. It shares the characteristic of being an internal, non-sensory organ with the Liver and Pancreas.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Human Organs as background academic context rather than a clinical decision trigger.
Understanding organ classification is fundamental in health assessment. A nurse assesses these organs differently: liver and kidney function are often monitored through lab tests (e.g., LFTs, RFTs) and observation for signs like jaundice or edema, while hearing assessment involves direct testing of the ear's sensory function.
A 'What if?' scenario: If the options were 'Stomach, Intestine, Liver, Heart', the Heart would be the odd one out as it's a circulatory organ, while the others are primarily digestive organs. This highlights the importance of identifying the primary system each organ belongs to.
What if? - If the stem changed one defining clue so that Ear no longer matched, reassess the option whose mechanism, classification, or indication now fits the revised presentation.

How to Approach the Question

First, analyze each word in the group to understand its basic definition and function.
Identify a common characteristic or category that links most of the words. In this case, 'Liver', 'Pancreas', and 'Kidney' are all internal organs.
Look for the word that does not fit into this established category. The 'Ear' is a sensory organ, not an internal visceral organ in the same sense.
Confirm the choice by verifying that the outlier is different based on a clear and consistent criterion (e.g., function, location, or type).
