Which of the following sentences is grammatically correct?

Question

Quizplus · Accepted Answer

Every sentence must contain a subject and predicate.
The subject of a sentence is the person, place, thing, or idea that is doing or being something. You can find the subject of a sentence if you can find the verb. Ask the question, "Who or what is performing the action in the sentence?" and the answer to that question is the subject.
The predicate is the part of a sentence or clause containing a verb and stating something about the subject.
" In spite of everything, he gave Peter a really extravagant gift after the argument." is correct because the subject is "he" and the predicate is "gave Peter a really extravagant gift after the argument."
Giving Peter a really extravagant gift after the argument, in spite of everything. is not grammatically correct because it is lacking a subject.
He gave Peter a really extravagant gift after the argument. In spite of everything. is not grammatically correct because the placement of the period results in the second half being an incomplete sentence.
To give in spite of everything Peter a really extravagant gift after the argument.is not grammatically correct because it is lacking a subject.
