21. Which static Processing sketch/program below reproduces the image to the right. It is the default 100x100 and does not change. The small square in the upper left corner is 10x10. Check ALL that apply. noStroke (); // choice A for (int i = 0; i < 10; i++) { rect (i, i, 10, 10); } noStroke (); // choice B for (int i 0; i < width; i=i+10) { rect (i, i, 10, 10); } noStroke (); // choice C int i 0; while (i < width) { rect (i, i, 10, 10); i=i+ 10; } = } = noStroke (); // choice D for (int i = 0; i < 10; i++) { rect (i*10, i*10, 10, 10); } noStroke (); // choice E for (int i = 9; i >=0; i--) { rect (i*10, i*10, 10, 10);
