Final answer:
The question pertains to a graphics operation in programming for drawing shapes. The correct method to draw both a rectangle and a square is 'FillRectangle' as it can adjust to the dimensions provided to either fill a rectangle or a square.
Step-by-step explanation:
The method mentioned in the question appears to be related to a computer graphics operation, specifically drawing shapes like a rectangle or a square on the screen. In many programming environments, these types of operations are conducted by calling particular functions or methods with specific parameters that define the size and position of the shape to be drawn.
Considering standard naming conventions in programming, for drawing a filled square, you would likely use a method called FillSquare because it explicitly states what shape it fills. However, if you want to draw a filled rectangle and potentially also a square (since a square is a specific type of rectangle with all sides of equal length), you would use a method called FillRectangle. The difference between 'Fill' and 'Draw' usually is that 'Fill' will create a solid shape with color filled in, while 'Draw' will only outline the shape.
To answer the student's question, the correct option would be [B] FillRectangle, as this method can be used to draw both a rectangle and a square, depending on the length of the sides specified in the arguments it receives.
