Show answer and explanation

Correct answer: (D) Configuration D

Explanation

A symmetric double-sided joint balances shrinkage across the plate thickness and reduces angular distortion. Configuration D also uses a smaller weld volume than the wider double-V alternative C, reducing heat input and contraction. Thus D is the least-distorting configuration among those shown.
