Question

In the following one of the cross section is ODD

}

• A. Option 1
• B. Option 2
• C. Option 3
• D. Option 4

Hint:

In cross-section questions, always compare symmetry, void pattern, and fibre packing arrangement to identify the odd figure.

Answer 1

The Correct Option is A

Concept: In fibre cross-section analysis, the odd one out is identified based on geometric structure, symmetry, and internal arrangement of voids or lobes. A cross-section that deviates from the common structural pattern of the remaining samples is considered the odd one.

Step 1: Observe the given cross-sections.
Among the four given figures, three cross-sections show a similar type of structural formation with repeating rounded/looped patterns and relatively uniform internal arrangement. However, one cross-section shows a distinctly different geometry and arrangement of internal structure.

Step 2: Identify structural difference.
The first cross-section (Option 1) exhibits a different fibre arrangement compared to the others. It does not follow the same repeating structural pattern seen in Options 2, 3, and 4. \[ \text{Option 1} \neq \text{Common structural pattern of others} \]

Step 3: Compare options.

• Option 2 → similar looped/structured pattern
• Option 3 → similar repeating structural geometry
• Option 4 → comparable patterned cross-section
• Option 1 → structurally different

Step 4: Final selection.
Thus, the odd cross-section is: \[ \boxed{\text{Option (A)}} \]
