Answer: Hey there! No worries about not being great at English, I'm here to help as much as possible! Upon considering the adjective and proper ways to use it, I believe B is the answer.
Step-by-step explanation:
First, let's help you get a better understanding of nouns and adjectives for future reference. Ask Any Difference offers this explanation for those looking to gain a better understanding of both terms: "The main difference between a noun and an adjective is that noun is used to identify a person, place, idea, or object, whereas adjective is used to connote a noun modifier. Adjectives are descriptive terms used in conjunction with nouns to specifically define the noun."
In simpler words, nouns (also called common nouns) are words that name things. Any non-specified person, job, place, object, idea is a noun. An adjective is the opposite and names nouns; words like "big", "silenced", "red", and "natural" are all describing words, and, therefore, adjectives.
Now, let's look at our answer choices:
A = "retail" is being used as a verb here, like how "sell" would be used.
B = this version of "retail" describes the opportunity.
C = like A, the term "retail" is being used in the way "sell" would be used. It is not an adjective (describing word).
As said above, B is the correct answer for this question. Though it was a bit long, I hope that explanation helps you out a little bit. You may not be exceptional in English now, but don't be hard on yourself; there's always room to learn and improve! :)
