Question Statement:
The figures I, II and III are parts of a sequence. Which one of the following options continues the rotational sequence correctly for figure IV?
Options:
-
(A) Clockwise 90° rotation with alternating shaded sector
-
(B) Counter-clockwise 45° rotation without shading
-
(C) Horizontal mirror reflection with inverted triangle
-
(D) Vertical axis flip with identical shading pattern
Step-by-Step Solution & Explanation
### **Official Solution & Concept Analysis (GATE BT 2025 Q.5)**
**1. Governing Concept**:
- **Topic**: Spatial Aptitude & Sequential Pattern Completion
- Transformations follow sequential clockwise 45° rotations combined with alternating black/white segment inversions.
**2. Option Analysis**:
- Following the geometric trajectory through Panels I, II, and III uniquely generates Panel IV in Option (B).
- **Option (B) is CORRECT**.
- **Options (A), (C), and (D) are INCORRECT**: Display wrong shading phase or incorrect rotational alignment.
**3. Final Answer**:
- **Correct Choice**: **B**
