27.White to move

In the position above as you can see Black has an advantage by two pawn.The question is

a)Is it possible for White to do something and prevent from losing?
b)Can Black easily win in this position?

Thanks again cikgu for solving problem 26 by 1.f7+ Kxf7 2.g8=Q+ Kxg8 3.Nf6+ Bxf6 4.Bb3 Bxc3+ 5.ka2 Qxb3 6.Kxb3 although Black has extra Bishop and a pawn it meaningless do to the colour of the Bishop.It cannot prevent White king from occupy the h1 Square and also promote the pawn.
