<span>C. He knows that Jean will regret it if she does not participate in the songs at school.</span>
Answer:
C
Explanation:
A has two commas too many (but, flounder, is) because there is no pause after but and flounder.
B has one comma too many (dirty, on the job) for the same reason as A
D can do without a comma (or, voters) because or is a conjunction that is mend to join words.
So therefore it must be C where the comma is used before the contrasting second part of the sentence, introduced by yet another conjunction.
Struggling very hard but it's not the ''Spell this or what is the definition''
