AI Explanation
The correct answer is C) mechanical seal. A mechanical seal is a device used to prevent leakage between a rotating shaft and the housing or casing in which the shaft operates. It is commonly used in pumps, compressors, and other rotating equipment. The illustration GS-0071 likely depicts a mechanical seal, which is the appropriate choice based on the question. The other answer choices, such as a soft-packing seal, quad seal, or spring seal, are not correct in this context, as they are different types of sealing mechanisms that serve different purposes and have different designs compared to a mechanical seal.
