the question below uses a robot in a grid of squares. the robot is represented as a triangle, which is initially in the bottom right square of the grid and facing toward the top of the grid. the following programs are each intended to move the robot to the gray square. program ii uses the procedure goalreached, which returns true if the robot is in the gray square and returns false otherwise. program i: repeat 4 times move_forward rotate_left move_forward rotate_right program ii: repeat until goalreached if can_move forward move_forward else rotate_left 31 mark for review which of the following statements is true? a program i correctly moves the robot to the gray square, but program ii does not. b program ii correctly moves the robot to the gray square, but program i does not. c both program i and program ii correctly move the robot to the gray square. d neither program i nor program ii correctly moves the robot to the gray square.

Answer

Answer:

B. Program II correctly moves the robot to the gray square, but program I does not.

Explanation:

Step1: Analyze Program I

Program I repeats a sequence 4 times. The sequence moves forward, rotates left, moves forward, rotates right. This pattern will not lead the robot to the gray - square as it has a fixed number of steps and turns that do not account for the grid layout to reach the destination.

Step2: Analyze Program II

Program II uses a "REPEAT UNTIL GoalReached" loop. Inside the loop, it checks if it can move forward. If it can, it moves forward; if not, it rotates left. This allows the robot to adapt to the grid and keep moving towards the goal until it reaches the gray - square.
