APV and NPV

when we simply look at the question and the question is asking us to evaluate whether to proceed with a project.

However, we know we have 2 methods that pop up in our mind which are APV and NPV

how do we know whether to calculate NPV or APV or NPV&APV ????

Because when i look at the past exam questions marks for those 3 instances above are similar to some extent….

i can’t see to differentiate whether to calculate NPV, APV or NPV&APV…
