Answer:

The correct option is Drop forging.

Explanation:

• In the majority of forging operations, a heated workpiece resting on a stationary lower die is pressed against an upper die.
• Drop forging is the technique when the higher die or hammer is dropped.
• Hammering hot metal into dies is known as drop forging.
• In press forging, heated metal is forced into a die with hydraulic pressure rather than being pounded into it with a hammer.
• Workpieces are placed inside dies and hammered until they take on the die's shape.
• The upper die is a moving hammer that is dropped into the workpiece in order to distort it, while the lower die is a stationary component.
• Most noise is produced in Drop forging.
