Answer:
B
Step-by-step explanation:
It says it wants the central idea for the last one, NOT the whole summary
So if we look at the last paragraph and its answers, it can't be D because it's not talking about lasagna and how it's made. It can't be C because that is a minor detail, or i think, but still, not describing the LAST paragraph.
A, or B?
I'd say B because A is stating the fact that, "each pasta HAS to be paired with THIS sauce" But it isn't it can be paired with any sauce, it's just that it would taste a bit gross. Which is exactly what B is stating.
