A broken piece of war plane wing found in the middle of an ocean had two propellers attached to it. Mid-tier war planes

[BTGmoderatorDC]

A broken piece of war plane wing found in the middle of an ocean had two propellers attached to it. Mid-tier war planes have at most three propellers attached to each wing. Hence the discovery clearly indicates that the wing belonged to a mid-tier war plane.

Which of the following, if true, most strongly supports the hypothesis?

A) Propellers were used only on war plane wings.
B) No mid-tier war plane design that is known only two propellers per wing.
C) The location at which the piece of wing was found also contained the remnants of several other war planes.
D) Propellers are the most economical and efficient means to provide additional thrust to a war plane during its flight.
E) The plane wing would not have been long enough to accommodate at least another 2 propellers as a whole.

A) Propellers were used only on war plane wings. WRONG. The argument talks of war planes . Not about whether war planes are only planes with propellers
B) No mid-tier war plane design that is known only two propellers per wing. WRONG: Argument talks about "AT MOST THREE" Could be two, could be one
C) The location at which the piece of wing was found also contained the remnants of several other war planes. WRONG: Argument does not talk about the location at all!
D) Propellers are the most economical and efficient means to provide additional thrust to a war plane during its flight. ABSOLUTELY WRONG
E) The plane wing would not have been long enough to accommodate at least another 2 propellers as a whole. CORRECT: The wing is not long enough for 4 propellers, that means wing can only have at the most 3 propellers: Correct
