Options two refers to the author being a teenager himself so he would be reliable for this info because it is firsthand.
I think the right answer is B, I could be wrong (sorry if I am wrong)
Cause and effect would be the correct answer because it's showing u the subject or in this case the cause and the effect would be what the cause does so if it's a tornado then the effect would be that it destroys
I think the answer is the second option!! Hope this helps!!
