What is the best practice for an if/else if/else with two independent booleans, where all four possible paths are distinct? [on hold]

I have two boolean expressions, A and B. I have four distinct paths which I must handle:

A and B
A and !B
!A and B
!A and !B

What would be the best way to check and define all four paths associated with the booleans? There are a few options, but each one seems to have dis/advantages. For example, this one is more readable (IMO; code is fairly self-explana), but evaluates A and B multiple times, which can be detrimental to performance if they are expensive operations.

if A and B
    # A and B
    path1()
else if A and !B
    # A and !B
    path2()
else if !A and B
    # !A and B
    path3()
else
    # !A and !B
    path4()

The next one evaluates A and B once each, but it isn't as immediately apparent which path is being evaluated. It also doesn't have the advantages of short-circuit evaluation.

if A
    if B
        # A and B
        path1()
    else
        # A and !B
        path2()
else
    if B
        # !A and B
        path3()
    else
        # !A and !B
        path4()

Is there a best practice to implementing this? Perhaps something I hand't considered?
