Not clear how this is mate. Why white can’t capture the black queen? Also why not queen promotion in the diagram and (c). ?

In twin a, 3.Kxa1(+bQd8)?? is illegal, because of 3…Qxh8(+wRa1,-wKa1). Also, 3.Qxa1(+bQd8)?? is illegal, due to 3…Qxb6(+wPb2,-wKb2).
In b, 3.Kxb1(+bQd8)?? Qxe8(+wSb1,-wKb1) and 3.Qxb1?? Qxb6, again.
In c, 3.Kxc1(+bQd8)?? Qxh8(+wBc1,-wKc1).
These moves explain the need for the specific type of the promoted pieces.

And another detail: b7 isn’t a flight square for the black king because of Kxb3.
