The diagram shows an arrangement of four meshed gears in a gear train.

Four adjacent meshed gears in a horizontal row: Gear A with 16 teeth, Gear B with 32 teeth, Gear C with 24 teeth, and Gear D with 48 teeth.

Each gear turns around a fixed axle. Gear A is rotated at a speed of 4.5 revolutions per second4.5\text{ revolutions per second}4.5 revolutions per second.

Which of the following options correctly describes the motion of Gear D?

speed: 1.5 revolutions per second1.5\text{ revolutions per second}1.5 revolutions per second; direction of rotation: same as A

speed: 13.5 revolutions per second13.5\text{ revolutions per second}13.5 revolutions per second; direction of rotation: opposite to A

speed: 1.5 revolutions per second1.5\text{ revolutions per second}1.5 revolutions per second; direction of rotation: opposite to A

speed: 13.5 revolutions per second13.5\text{ revolutions per second}13.5 revolutions per second; direction of rotation: same as A
