The correct answer is: D. None of the above

A jumper is a tool used for dressing stones. It is a type of chisel that is used to shape and smooth stones. Jumpers are typically made of steel and have a long, narrow blade. The blade is sharpened on one side and has a groove on the other side. The groove helps to guide the jumper along the stone as it is being cut.

Jumpers are used by stonemasons and other professionals who work with stone. They are also used by hobbyists who enjoy working with stone. Jumpers can be purchased from most hardware stores or online.

Here is a brief explanation of each option:

• Option A: Testing of stones. This is not the correct answer because jumpers are not used to test stones. Stones are typically tested using a variety of other tools, such as hammers, chisels, and gauges.
• Option B: Quarrying of stones. This is not the correct answer because jumpers are not used to quarry stones. Quarrying is the process of extracting stones from the ground. This is typically done using large machines, such as excavators and bulldozers.
• Option C: Dressing of stones. This is the correct answer because jumpers are used to dress stones. Dressing is the process of shaping and smoothing stones. This is typically done using a variety of tools, such as hammers, chisels, and jumpers.
