c. before the conjunction
When combining two sentences (or independent clauses) using a conjunction, the comma must be placed before the conjunction. This tells the reader that one complete idea is over, but there is another idea attached to it that adds more information. The second independent clause is stopped with a period so no further punctuation is necessary.
