Your question is unclear.
Changing the order of the denominator doesn’t change the product. 4•6=24 and 6•4=24 again.
I think that your answer would be B) lines that meet at a 90 degree angle. These lines must intersect, and they have slopes that are opposite reciprocals when compared to each other.
I believe it would be A) checks and debit cards both withdraw money directly from the bank account. Although checks do not automatically withdraw, it will take a few days. Hope this helps!
