The use of heat pumps has been held back largely by skepticism about advertisers' claims that heat pumps can provide as many as two units of thermal energy for each unit of electrical energy used, thus apparently contradicting the principle of energy conservation.

4.  If the author's assessment of the use of heat pumps (lines 1-3) is correct, which of the following best expresses the lesson that advertisers should learn from this case?
(A) Do not make exaggerated claims about the products you are trying to promote.
(B) Focus your advertising campaign on vague analogies and veiled implications instead of on facts.
(C) Do not use facts in your advertising that will strain the prospective client's ability to believe.
(D) Do not assume in your advertising that the prospective clients know even the most elementary scientific principles.
(E) Concy on financially relevant issues such as price discounts and efficiency of operation.
