(a) 1010.2 millibars

Answer 2

the right alternative is (c). The universal Standard Atmosphere (SA) sets the normal barometrical weight adrift dimension to be 1013.25 hPa (hecto-Pascal, that supplanted the millibar).

It additionally sets the normal temperature to be 15 C and, the normal adiabatic slip by rate (how chilly it gets with height) to be 0.65 C per 100 meters.  

The Standard Atmosphere is the thing that all instruments are adjusted for.

It implies that if, for instance, you fly amid the winter (as I did prior today) you will fly a bit lower than what your altimeter demonstrates on the grounds that the air is colder than 15 C and denser.
