Pressure decreed as height increases Due to low suction pressure compressor will require more power.

At high altitude, the less power will require because compression ratio will be less.
So Answer B is correct.
So Answer B is correct.

Why is it so?

At higher altitudes molecules of air are few, hence a compressor supplies smaller volume of air at a higher altitude so it requires less power.

As per my opinion, at high altitude power required to compressed air is more because temperature of air at height is more & Pressure is less Called less dense air. So specific volume of air is high due to high temperature & compressor consumes more power for same pressure ration on sea level to compress high temperature air.

From my point of view answer is more power is required.

In my opinion, in high altitude the pressure is very low so higher power is required to reach the desired than sea level for same compressor ratio. So higher power is required.

Yes, higher power required.
Omkar said:

More power is required for same compression ratio.

For same compression ratio, discharge pressure is low because of low suction pressure at higher latitudes so power required is less. At higher pressure, further compression required more power.
