Answer:
First one: Economic Order; Second One: Safety Stock
Explanation:
I know the second one's right because it frequently shows up on PLATO modules for business. The first one is economic order according to investopedia.com. I looked up both carrying quantity and just in time quantity, too-- it seems as carrying quantity isn't a thing, and just in time quantity focuses on decreasing waste. See my comments on your question for quotes from the source.
Hope this helps you!!
