The question below uses a robot in a grid of squares. The robot is represented as a triangle, which is initially in the bottom left square of the grid and facing right.

The figure presents a robot in a grid of squares with $5$ rows and $4$ columns. The robot is represented by a triangle which is initially in the lower left square of the grid, facing right. The grid contains a gray square in the first row and third column 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.

The figure presents two programs, labeled Program $1$ and Program $2.$ Program $1$ has a block of code that consists of six lines. Throughout the code there are nested blocks of code. $[$Begin Block$]$ Line $1$: REPEAT $2$ TIMES $[$Begin Block$]$ Line $2$: $[$begin block$]$ MOVE$\_$FORWARD $[$end block$]$ Line $3$: $[$begin block$]$ ROTATE$\_$LEFT $[$end block$]$ Line $4$: $[$begin block$]$ MOVE$\_$FORWARD $[$end block$]$ Line $5$: $[$begin block$]$ MOVE$\_$FORWARD $[$end block$]$ Line $6$: $[$begin block$]$ ROTATE$\_$RIGHT $[$end block$][$End Block$][$End Block$].$ Program $2$ has a block of code that consists of $5$ lines. Throughout the code there are nested blocks of code. $[$Begin Block$]$ Line $1$: REPEAT UNTIL $[$begin block$]$ GoalReached $[$end block$][$Begin Block$][$Begin Block$]$ Line $2$: IF $[$begin block$]$ CAN$\_$MOVE $[$begin block$]$ forward $[$end block$][$end block$][$Begin Block$]$ Line $3$: $[$begin block$]$ MOVE$\_$FORWARD$][$end block$][$End Block$]$ Line $4$: ELSE $[$Begin Block$]$ Line $5$: $[$begin block$]$ ROTATE$\_$LEFT $[$end block$][$End Block$][$End Block$][$End Block$][$End Block$]$

Which of the following statements best describes the correctness of the programs?
