Question

WHICH ONE IS CORRECT ANSWER?

Consider writing code that starts with the image "astrachan.jpg" shown below on the left and replaces the bottom 10 rows
of pixels with black pixels, resulting in the picture on the right below.
The code has been started below but has missing code.
var image = new Simplelmage("astrachan.jpg");
// missing code
print(image);
Which one of the following is the best choice for the correct missing code to replace the bottom 10 rows with black pixels?
var height = somelmage.getHeight();
for (var pixel of somelmage.values()) {
if (pixel.getY() <= height - 10) {
pixel.setRed(0);
pixel.setGreen(0);
pixel.setBlue(0);
}
var height = somelmage.getHeight();
for (var pixel of somelmage.values()) {
if (pixel.getY() >= height - 10) {
pixel.setRed(0);
pixel.setGreen(0);
pixel.setBlue(0);
}
}
var width = somelmage.getWidth();
for (var pixel of somelmage.values()) {
if (pixel.getX() <= width - 10) {
pixel.setRed(0);
pixel.setGreen(0);
pixel.setBlue(0);
}
}
var width = somelmage.getWidth();
for (var pixel of somelmage.values()) {
if (pixel.getX() >= width - 10) {
pixel.setRed(0);
pixel.setGreen(0);
pixel.setBlue(0);
}
