<span>the word is "vocabulary"</span>
Answer:
I would say D
Explanation:
A is just stating simple, obvious, even useless information
B is a little more opinion than about the necessity
C is not really helpful "but they are wrong" isn't a great statement for a persuasive essay, especially the conclusion and does not really suport the necessity
D points out the need
I would go with C. Being a repentant sinner
