The correct answer is D. Dipper shovel.
A dipper shovel is a type of earthmoving machine that uses a bucket to dig and move material. It has a short cycle time because the bucket can be quickly raised and lowered, and the machine can be easily maneuvered.
A drag line is a type of earthmoving machine that uses a cable to drag a bucket along the ground. It has a longer cycle time than a dipper shovel because the bucket must be lowered and raised slowly, and the machine is not as maneuverable.
A hoe is a type of earthmoving machine that uses a blade to push material. It has a longer cycle time than a dipper shovel because the blade must be raised and lowered slowly, and the machine is not as maneuverable.
A clam shell is a type of earthmoving machine that uses a pair of jaws to open and close. It has a longer cycle time than a dipper shovel because the jaws must be opened and closed slowly, and the machine is not as maneuverable.
