Answer:
b) Not refined or processed.
Step-by-step explanation:
The word "crude" is used to refer to the natural state of something, without any changes done to it. This means that 'crude' refers to things that are in their original condition without undergoing any change or correction.
In the given passage, the speaker talks of "crude oil from Lake Maracaibo . . . to be made into gasoline, kerosene, and diesel oil." This means that the oil that they got from the lake is in its original state, before any process is done on it to change its properties. This, in short, means the oil is unrefined or not yet processed.
Thus, the correct answer is option b.
