What does the 'change()' method do when the current color is RED?

  1. Changes color to GREEN

  2. Changes color to YELLOW

  3. Changes color to RED

  4. Does nothing

The correct answer is: Changes color to GREEN

The 'change()' method changes the current color to a new color. When the current color is RED, the method changes it to GREEN. This means that the other options, changing the current color to YELLOW or RED, are incorrect. Additionally, the option stating that the method does nothing is also incorrect, as the whole purpose of the method is to change the current color.
