C is the correct option.
If the surface air pressure is 1,000 mb, the air pressure at 1 km above the surface will be: The air pressure decreases by 1 mb for every increase bof 10 m in height
Since, height increased = 1 km
Air pressure decrease by units = 1000/10 = 100 units
If the surface air pressure is 1,000 mb, the air pressure at 1 km above the surface will be: The air pressure decreases by 1 mb for every increase bof 10 m in height
Since, height increased = 1 km
Air pressure decrease by units = 1000/10 = 100 units
Hence, pressure at 1 km above will be
1000 - 100 = 900 mb
1000 - 100 = 900 mb

Air Pressure at Altitude
Atmospheric pressure decreases with altitude. The pressure at sea level is around 1013 millibars (mb), which is equivalent to 1 atmosphere (atm) of pressure. As you go up in altitude, the air becomes less dense and the pressure decreases. This is because there is less air above you pushing down on you.
Formula for Calculating Air Pressure at Altitude
The formula for calculating air pressure at altitude is:
P = P0 * e^(-h/H)
where:
P = pressure at altitude
P0 = pressure at sea level (1013 mb)
e = Euler's number (2.71828)
h = altitude in meters
H = scale height (7,400 meters)
Answer Explanation
Given that the surface air pressure is 1,000 mb, we can use the formula above to calculate the air pressure at 1 km above the surface.
P = P0 * e^(-h/H)
P = 1000 * e^(-1000/7400)
P = 900 mb
Therefore, the air pressure at 1 km above the surface is 900 mb, which is option C.
