Final answer:
The complete sentence is 'For breakfast, this restaurant serves eggs with biscuits and gravy.' as it contains both a subject and a predicate and conveys a full thought. The correct option is B. *For breakfast, this restaurant serves eggs with biscuits and gravy.*
Step-by-step explanation:
Among the provided options, the sentence 'For breakfast, this restaurant serves eggs with biscuits and gravy.' is a complete sentence. A complete sentence must have at least one subject and one predicate. The subject here is 'this restaurant,' while the predicate is 'serves eggs with biscuits and gravy.' The sentence also conveys a complete thought, indicating what the restaurant serves for breakfast.
On the other hand, the phrase 'Displays her most prized possessions on the mantel in the living room.' lacks a subject and a verb, and it does not express a complete thought when standing alone. It could be part of a complete sentence, but as it stands, it is not.
A complete sentence is a sentence that expresses a complete thought and contains both a subject and a predicate. It can stand alone as a meaningful statement or question. In the given options, the complete sentence is A. "Displays her most prized possessions on the mantel in the living room." This sentence has a subject ("she") and a predicate ("displays her most prized possessions on the mantel in the living room").
The correct option is B. *For breakfast, this restaurant serves eggs with biscuits and gravy.*
