The following structures are designed to store information about objects in a Cartesian coordinate system 9. struct point fint x, y): struct rectangle sint upper left x, upper left_y, lower_right x, lower_right y;) A point structure stores the x and y coordinates of a point. A rectangle structure stores the coordinates of the upper left and lower right corners of a rectangle. Which of the following functions will correctly determine whether a point p lies within rectangle r, return 1(true) or O(false)? a) int is-inside (struct point p, struct rectangle r){ return p.x > r. upper-left-y r.upper-left-x && p.x = b) int 13-Inside (struct point p, struct rectangle r){ return p.x > r.upper-left-y r. lower-right-x && p.x = C) int 13-inside (struct point p, struct rectangle r){ return p.x >= r.upper-left-X && p.x = a) int is-inside (struct point p, struct rectangle r){ return p.x >= r. upper-left-x && r . upper-left-y; } && r. lower-right-X r. lower-right-y p.x = && p-Y
