Explanation

Guitar because it is a string instrument (a chordophone), where sound is produced by plucking or strumming its strings.
The other three options—Conga, Tabla, and Gongs—are all percussion instruments.
Percussion instruments produce sound when they are struck, shaken, or scraped.
The fundamental difference lies in the method of sound generation, making the Guitar the one that does not fit the group's pattern.

Option B: Conga is a percussion instrument, similar to Tabla and Gongs. It fits the pattern of the group.
Option C: Tabla is a percussion instrument, similar to Conga and Gongs. It fits the pattern of the group.
Option D: Gongs are percussion instruments, similar to Conga and Tabla. It fits the pattern of the group.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Musical Instruments as background academic context rather than a clinical decision trigger.
This is a general intelligence and reasoning question, often included in the non-nursing section of competitive exams to assess logical deduction.
There is no direct clinical relevance for this question in the context of nursing practice.
What if? If the options were 'Violin, Sitar, Cello, Flute', the answer would be 'Flute' as it is a wind instrument, while the others are string instruments.

How to Approach the Question

Read the question carefully to understand the task, which is to find the 'odd one out'.
Analyze each option and identify the category or group it belongs to. In this case, the category is the type of musical instrument.
Classify each instrument: Guitar (String), Conga (Percussion), Tabla (Percussion), Gongs (Percussion).
Identify the common characteristic shared by the majority of the options. Here, three of the four are percussion instruments.
The option that does not share this common characteristic is the correct answer.
