Btack weld
Cplug weld

AI Explanation
The correct answer is D) fillet weld. A fillet weld is a type of weld with a triangular cross-section that is used to join two surfaces at right angles to each other. This is the defining characteristic of a fillet weld, which makes it the correct answer choice. The other answer options are incorrect because: A) A seam weld runs along the joint between two pieces, rather than forming a triangular cross-section. B) A tack weld is a small, temporary weld used to hold pieces in place, not a permanent joining method. C) A plug weld is a circular weld used to join two overlapping pieces, not a triangular fillet weld.
