Hello!
I think the answer is Option A.
This is the best way to fix this run-on sentences.
Remember, we can fix them with a comma, a semicolon and a period and FANBOYS (for, and, but, or, yet, so).
Keep the mnemonic in your memory. :)
We fix this sentence with "so".
Hope it helps!
Ask me if you have any query.
