Final answer:
The incorrect use of the vocabulary word is found in 'The eclectic appliances were useless when the power was out,' (option A) since 'eclectic' does not correctly describe the utility of appliances during a power outage.
Step-by-step explanation:
The sentence in which the vocabulary word is being used incorrectly is:A) The eclectic appliances were useless when the power was out.The word 'eclectic' means deriving ideas, style, or taste from a broad and diverse range of sources, especially to form a cohesive whole.
It is not used correctly in this context because 'eclectic' does not describe the function of appliances during a power outage. Rather, it suggests a diverse collection or variety. The correct usage of 'eclectic' would typically refer to an assortment, such as 'Her living room is furnished with an eclectic mix of antique and modern pieces.'
