Answer:
The correct answer is letter "A": It is a loaded question.
Explanation:
Loaded questions are those that carry a mistaken assumption. Often, loaded questions tend to cause uncomfortable feelings to the individuals being asked since the question forces an answer that the individual may disagree with. Loaded questions are considered unethical.
In the case, the question:
"How much do you like the superior qualities of ABC Soap?";
is assuming the audience likes ABC Soap, in the first place, and that they enjoy its "superior qualities" even if people might not be aware of them.
