An office building has two floors. A computer program is used to control an elevator that travels between the two floors. Physical sensors are used to set the following Boolean variables.

The figure shows a table with 2 columns and 5 rows. The top row contains the column labels, from left to right; column 1, Variable; column 2, Description. From top to bottom, the data is as follows: Row 2; Variable, onFloor1, Description, set to true if the elevator is stopped on floor 1; otherwise set to false. Row 3; Variable, onFloor2, Description, set to true if the elevator is stopped on floor 2; otherwise set to false. Row 4; Variable, callTo1, Description, set to true if the elevator is called on floor 1; otherwise set to false. Row 5; Variable, callTo2, Description, set to true if the elevator is called on floor 2; otherwise set to false.

The elevator moves when the door is closed and the elevator is called to the floor that it is not currently on. Which of the following Boolean expressions can be used in a selection statement to cause the elevator to move
