Which of the following is NOT a basic type of lifting bag?

Explanation:
The primary idea is that lifting bags are categorized by the pressure they operate at. High-pressure bags are compact and deliver a lot of force in a small area, useful in tight spaces. Low-pressure bags have a larger volume and lift more gradually, distributing the load over a bigger area. Some lines also offer a middle/medium option, but that’s less common and simply sits between the extremes. Pneumatic, on the other hand, describes the power source (air-driven) rather than a specific pressure rating. Since the basic classification here is about pressure levels, pneumatic isn’t a fundamental type of lifting bag.
