The correct answer is A. The freshest store in town
Explanation:
In grammar, a phrase is a set of words that compose a unit and express some idea or have a meaning but do not contain a main verb and subject and because of this, phrases are not considered as a sentence or complete thought. Instead, most phrases are used to complete or expand the meaning of sentences, which are units containing a subject, an action and in most cases a sentence complement. This also implies sentences can contain multiple phrases. Considering the previous information, in the case of the sentence "Keith will only buy his groceries at B & B Markets, the freshest store in town" the phrase is "The freshest store in town" because this section of the sentence does not contain the action or subject but still has some meaning, also this group of words complements and expand the message of the sentence which the way a phrase works.
