Quizplus · Accepted Answer

The technique described in the question is commonly known as batching, where different grades of crude oil or products are transported through the same pipeline at the same time without mixing. This is achieved by using a batching pig, which is a device inserted into the pipeline that separates the different products by creating a physical barrier between them. Option B, batching pig, best describes the technique mentioned in the question. Options A, C, and D are not relevant to the explanation.
