Answer :
☁️My Answer☁️:
I believe B. Felix is going to the lake to catch a large fish, which we will eat for dinner tonight is the correct answer because it has most of the elements to make a complete sentence which are, capital Letter, subject Noun, predicate verb, complete thought, and terminal punctuation. Although B. does not contain all of the elements to a complete sentence it does include most.
✧My Explanation✧:
We can already see the answer choice A. Am going to the lake is an answer to eliminate because this an incomplete sentence, it is one that does not express a full thought (also referred to as sentence fragments which usually do not include both a subject and a verb).
We can already see the answer choice C. Enjoy eating dinner is an obvious answer to eliminate because this is also a incomplete sentence, as it does not contain most or all of the elements to a complete sentence.
