1. c8=Q+ Ka7 2. Qc7+ Ka8 (if Ka6 then Bc8++) 3. Bg2+ Be4 4. Qd8+ Ka7 5. Qe7+ and wins the Black Bishop
Maybe, but White still has work to do. Unfortunately he can’t capture the bishop with his queen, because he’ll be left with insufficient mating material.

its importaint, that black cant cover the b7 square and has no check after
4…Kb8
5. Bxe4
The solution is :
1.c8Q+ Ka7 2.Qc7+ Ka8 3.Bg2+ Be4 4.Qh7!
[4.Qd8+?! Ka7 5.Qe7+ Kb6 6.Bxe4 Qc1 7.Qb7+ Ka5 very slight advantage for White]
4…Kb8 5.Bxe4+- (threatens Queen & mate)
