The question asks which of the given function calls would be legal for the defined function greet(labelSize, color): Label('Hi', 100, 100, fill=color, size=labelSize).
Option 1: greet(20, 60) — Here the first argument is 20 (a number), but the second argument is 60 (another number). Since the color parameter is intended to be a color value or color-like string, passing an integer for color is likely invalid or at least not matching the expected type. So this call is dubious and generally considered invalid in typical usage.
Option 2: greet(20, 'blue') — The first argument is 20, which would map to labelSize, a numeric size. The second argument is 'blue', a string, which can represent a color value consumable by fill=color in the Label call. This matches the expected types and would be a legal function call.
Option 3: greet('white', 40) — The first argument is 'white', a string, which would be passed as labelSize. Since labelSize is used as the size parameter, providing a string where a number is expected would cause a type error or runtime error. Therefore this is not legal.
Option 4: greet('yellow', 'pink') — Both arguments are strings. The first should be a numeric labelSize, so passing 'yellow' as the labelSize would be invalid, and the second as a color string might be fine, but the mismatch in the first argument makes the overall call invalid.
In summary, the only option that aligns with the expected parameter types (numeric labelSize and color value/string for fill) is the second one, greet(20, 'blue').
