AI Explanation
The correct answer is A) form tools. Form tools, also known as profile tools, are used to create specific shapes or contours on a workpiece. They have a predetermined shape that matches the desired profile to be cut. This makes them well-suited for the application shown in the illustration GS-0090, where specific forms or curvatures need to be produced on the lathe. The other options are incorrect because: B) curvature cutting tools is not a standard term, C) parting tools are used to separate or cut off parts of the workpiece, and D) universal turning tools refer to general-purpose tools, not specifically shaped ones.
