Since the white king is in check, one piece has to be interposing the bishop in order to have a valid position.
Which pieces would you prefer? #2

rook and pawn offers really the only good chance of winning (generally speaking)...since there's no obvious win as with the other options and the rook+pawn represent some kind of dynamic material imbalence to make the position more interesting, but bla bla bla bla bla, it depends on the position, since you can set the configuration of pieces to win for you immediately, the usual garbage stuff..... zzzzzzzzz

Macer, clifton is laughing at you, Be7 holds for black.
No, my comment was for MainlineNovelty.
Which pieces would you prefer in this position as white, assuming that they can be anywhere in the starting position with black to move.
NOTE: Position has to be legally reachable.
Choices:
A - 2 Bishops
B - Bishop + Knight
C - 2 Knights
D - Rook + Pawn
