The function swapRedGreen has one parameter, a pixel. This function swaps the red and green values and returns the resulting red, green and blue values somehow. Which one of the following is the correct code for this function?

// write your code here
function swapRedGreen(pixel) {
     var newGreen = pixel.getRed();
     var newRed = pixel.getGreen();
     pixel.setGreen(newGreen);
     pixel.setRed(newRed);
     return pixel;
}
var image = new SimpleImage ("eastereggs.jpg");
print (image);
for ( var pixel of image.values()){
    if (swapRedGreen(pixel) ){
       
    }
   
}
print (image);
