Athe first pass of the weld is to be back gouged
Bthe arrow side of the weld is to be surface finished
Cthe opposite side of the weld is to be surface finished
Da "V" groove weld is to be made
AI Explanation

The correct answer is D) a "V" groove weld is to be made. The inverted "V" symbol on the welding reference line indicates that a "V" groove weld is to be made. This is a common welding symbol that specifies the joint preparation required, in this case a "V" shaped groove that the weld metal will fill. The other answer choices are incorrect because they do not accurately describe the meaning of the inverted "V" symbol. Option A refers to back gouging, option B refers to surface finishing on the arrow side, and option C refers to surface finishing on the opposite side - none of these match the meaning of the inverted "V" welding symbol.
