The question was asked by my school principal while I was bunking the class.

This intriguing question comes from Prediction of Execution Times in chapter Embedded Operating System, Middleware and Scheduling of Embedded Systems

Answer 1

Right answer is (b) accurate cost and performance value

The best I can explain: The accurate cost and performance value is possible if interfaces to software synthesis tools and hardware synthesis tools exist and is more precise than any other methods.
