Tie for Two:
B & C are both Expanded Form
A & B both show 40+8 clearly
B & D are almost identical (they show the same subtractions in vertical form)

Thread for Three:
B, C, & D are all “long” division
A, B, & D all have the same subtractions (partial quotients)
A, B, & D use the fewest steps
A, B, & D start by subtracting 160

Fit for Four:
All use the same equation
All have the same quotient
All subtract 32 for the last step
