I believe it's B. Lower grade of plastic due to recycling. No promises though.
The best answer would be B because, for instance, if someone is bothering you and you tell the teacher, you say how you feel if you don't know, it just wouldn't make sense. You get what I am trying to say right?
I hope this helps:)
The easiest one would be the single-entry system
the accounting in single entry system only cover the "bare essentials" in its book such as cash, product, and account payable"
It's really simple and way cheaper to maintain compared to the double-entry system. Which cover all the transactions, even the one one that haven't happen yet
