From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences. Their shop stocks _...

The correct option for the sentence "Their shop stocks _____ overwhelming variety of goods" is: an. The sentence describes the variety of goods available at a shop, which is described as "overwhelming." The word "overwhelming" means that there are so many goods available that it's difficult to choose or decide. Therefore, we need an article that describes the noun "variety" in a singular form, and the appropriate article in this context is "an". The options "any," "every," and "each" are not appropriate in this context because they are not used to describe a singular noun, but rather they are used to describe a general or indefinite reference to a group of nouns. Therefore, they do not accurately convey the meaning intended by the sentence.
