Sagot :
In a sentence where there are two separate independent clauses, the comma should be placed before the conjunction. The correct answer is therefore c) before the conjunction. There are some instances where the comma will not be needed, for example where both independent clauses are short or mean similar things. However, c) is the correct answer for this question. Hope this helps!
The correct answer is C. before the conjunction.
If there is a conjunction between two independent clauses, then the comma will be placed in front of it. For example: We had a lot of fun at the beach, but I feel tired now.
As you can see, the comma is located in front of the conjunction but. Simply placing a comma between the sentences (without a conjunction) creates a run-on sentence, and that is grammatically incorrect.
