Final answer:
To scale a shape outward from the center, use the Scale Tool, possibly with the Shift key for proportional scaling; dragging corners or using the Rotate Tool will not achieve this uniformly.
Step-by-step explanation:
To scale a shape outward from the center, typically in graphic design software or a CAD (Computer-Aided Design) program, the correct method would be to use the Scale Tool. The Scale Tool allows you to uniformly scale an object about its center or a specified reference point. If you want to maintain the proportions of the shape while scaling, you may hold the Shift key while dragging. This ensures that the shape scales evenly in all directions from the center point. Simply dragging one of the corners without holding any modifier keys may scale the shape disproportionately, and using the Rotate Tool would only change the orientation of the shape, not its size. Therefore, c) Use the Scale Tool is the correct answer to the question.
