I hear you. However, what I was saying is that by asking a question about VMCA, you must automatically assume engine failure Therefore, that would also make c) correct...
Typical CAA wording I guess. Below VMCA (which is a speed that only applies to a failed engine scenario) the aircraft is uncontrollable... Straight and level flight cannot be maintained below VMCA...yes agreed, but the use of uncontrollable and VMCA in the same sentence seems to make sense also..
