A booking system for a city bus service prices its fares according to the time of travel:

* Peak-time tariff starts at 0600 and finishes at 1000 am

* Off-peak tariff applies during all other times of service

* The bus service does not operate between 2300 and the start of the next day's peak service

Note that all times mentioned are inclusive.

When applying the equivalence partitioning test design technique, which of the following options, shows test case inputs that each fall into a different equivalence partition?

Okay, I think I've got this. The key is to identify the different time periods - peak, off-peak, and the time when the service is not operating. Then I can choose test cases that fall into each of those partitions.

I feel pretty confident about this one. The key disadvantages seem to be around security, control, and complexity when you have a mixed hardware setup rather than a uniform system. I'll go with options C, D, and E.

Okay, I've got a strategy here. I'll focus on identifying the response that best captures the balance between level of detail and addressing the unique needs of different employee groups.

I appreciate how B cleanly separates the different fare periods. Makes it easy to test the system's behavior.

Haha, D is just trying to be tricky with the 2400 time - nice try, but I'm not falling for that one!

Hmm, I was stuck between B and C, but B does a better job of hitting those critical time slots. Good call.

Because the times in option C fall into different equivalence partitions - off-peak, peak, and outside of service hours.
