You left out the main point of the problem!
The stipulation should be "White to play - what result?" since there can be no other result, even if White does not want to win.
1 resignation by white
2 draw offer
3 timeout
4 mating combination.
and 4 subvariations of option four where black promotes with N, R, B or Q
Originally posted by flexmore2 and 3 are the same if the game is played by FIDE rules; White can't lose on time because he can't get checkmated even with the worst possible play.
there are 4 main variations:
1 resignation by white
2 draw offer
3 timeout
4 mating combination.

But in the case of a chess problem, arbitrary human actions such as draw offers and resignation shouldn't even be considered. Under problem conventions, there is only one possible result.
