During a protracted siege, which outcome becomes very likely when miners undermine a castle wall using shoring beam removal?

A)Abrupt wall section collapse inwards✓

B)Gradual settling cracks throughout wall

C)Compaction occurs within the moat

D)Increased defender ranged weapon effectiveness

💡 Explanation

Undermining a castle wall weakens its base supports because stress concentration exceeds the material strength, causing sudden catastrophic failure via brittle fracture. Therefore, the wall collapses abruptly inwards rather than settling gradually, because shoring removal triggers immediate instability.
