The answer to this is letter B. You can expect that W. Partitions exercised, X. Boundaries exercised, and Y. State transitions will all be used in order to make sure that the whole testing can be done effectively. Take note that this is the best possible answer based on the given but if the right answer will be used, it is best that V will also be included. V stands for decision outcomes exercised that will matter a lot.
If all of these will be used, then the testing will go on smoothly and as planned. Take note that there may be some modifications depending on the type of testing that will be done.
