Consider an online application that allows registered users to pay the annual car tax based on the vehicle's engine power in kW. Given the following user story:"As a customer I need the online application to calculate the annual car tax amount that I need to pay for my car":- If the power of the vehicle is less than 20 kW, then the annual car tax is free- If the power of the vehicle is more or equal than 20 kW but less or equal than 150 kW, then the annual car tax is 250 Euros- If the power of the vehicle is more than 150 kW, then the annual car tax is 750 Euros"What is the MOST suitable use of a black-box test design technique for this user story?

1. A. State transition testing. Test the transitions between the following states: logging in, inserting the power of the vehicle, making payment, logging out
2. B. Use case testing.Test the following use case (Actor=registered user):Pre-condition=registered user logged inScenario=registered user inserts the power of the vehicle, making payment and logs outPost-condition=car tax paid and registered user logged out
3. C. Decision table testing. Test the following conditions:Conditions=registered user logged in; inserted power of the vehicle=20kW;Action=Car tax paid
4. D. Equivalence partitioning. Test the annual car tax value for the following partitions:[power of the vehicle 150 kW] — đáp án hiện tại
