which line in the following program will cause a compiler error?

18. Fill in the blank so that this function returns true if the circle at xl, yl, with radius rl, has collided with the circle at x2, y2, with radius r2. boolean collided (int xl, int yi, int ri, int x2, int y2, int r2) | return A. dist (xl, yl, x2, y2) <= rl+r2 B. abs (x1-x2) >= rl+r2 && abs (yl-y2) <= rl+r2 C. A and B will both work D. Neither A nor B work but one would be correct if the <= was > E. Neither A nor B work but both would be correct if the <= was >

24. Consider the Insertion Sort (code 3) algorithm described in the appendix. How can we change this code to have the algorithm sort from largest to smallest instead? (A) Change line 9 to: a[j-1] = a[j]; (B) Change line 7 to: while(j >0 && a[j - 1] 0; i--) (E) Change line 12 to: a[i] = x;
