White can now win by force, so answer C) is correct.
67.d5+!
Eventually conquering the bishop on d3 - or the rook on e1! [Instead, after 67.Rxb7
Rxe4+
68.Kg3
(68.Kg5?
Be2!
would draw immediately.) 68...Re3+
White's victory would be most problematic.]

and Black resigned in view of the line

and now the final point:
72.Bc3+!
1-0
