B Correct answer
Explanation

QNH is the pressure setting that reduces aerodrome pressure to mean sea level (MSL) under International Standard Atmosphere (ISA) conditions. QFE is the actual pressure at the aerodrome elevation, QNE is the pressure at the transition altitude, and QFF is MSL pressure using actual (not ISA) temperature conditions.
