Think of an ATM. If you enter a correct PIN, it gives you cash. If you enter a wrong PIN once, it lets you try again. But if you enter a wrong PIN three times (previous history), the ATM locks your card (changes state). The ATM reacts differently to the exact same action based entirely on what happened before.
C: State transition testing Specifically used when the system’s response depends on its current state (condition) and previous history (how it got there).
I think C is the correct answer. A for sure is not because is not a black box technique. D is not because it has nothing to do with the current state or history. C seems the most suitable answer in my opinion
