Answer:
Option (A)
Explanation:
See attachment for options
From the options, the code segment of option (A) answers the question and the explanation is as follows:
I added a second attachment which illustrates the movement
function (solveMaze) {
moveForward(); ---- The robot moves up (to position 1)
moveForward(); ---- The robot moves up (to position 2)
rotateRight(); ---- The robot changes where it faces (however, it is still at position 2)
while(canMove("forward")) { moveForward(); } ---- This is repeated until the robot reaches the end of the grid (i.e. position 3 and 4)
rotateLeft(); ---- The robot changes where it faces (however, it is still at position 4)
moveForward(); ---- The robot moves up to the gray square
