Question

Anyone knows which combine of the two sentences below using a coordinating conjunction? If you do know please give an explanation that makes sense

Answer 1

Answer: A

Step-by-step explanation:
Of course, I would choose between A or B.
This is another tricky one, but according to my knowledge I would have choose A.
Try eliminating them it would make better sense and easier, like the ones that don't make any sense at all. Like C, it is correct but it's just a whole sentence without any coma's or anything. That's the first thing I would eliminate.
