⭕ A. 44 mm
⭕ B. 41 mm
⭕ C. 38 mm
⭕ D. 35 mm
📚 Explanation:
In Indian Railways, for broad gauge (BG) tracks, the minimum crossing clearance is an important dimension to ensure smooth and safe movement of rolling stock at turnouts and crossings.
🔹 The standard minimum clearance at crossings for broad gauge is 44 mm.
🔹 This ensures proper wheel flange clearance and reduces wear.
🔹 Excessive clearance leads to derailments, while inadequate clearance causes jamming.

👉 Therefore, the correct answer is: A. 44 mm
Key Points on Broad Gauge Crossing Clearances:
- Applies to standard Indian Broad Gauge (1676 mm)
- Ensures safety at crossings and turnouts
- Minimizes wheel and rail wear
- Defined by Indian Railway Permanent Way Manual
- Must be maintained precisely during track maintenance
