What is Malcolm Gladwell’s take on why pilots from certain countries are more likely to crash planes?

A  In certain countries, air traffic controllers aren’t trained very well, and they thus inadvertently induce pilots to crash their planes.

B  In certain countries, pilots aren’t trained properly and thus go onto crash their planes.

C  They had lower power distance communication styles and didn’t listen to the air traffic controllers that could help them out of a bad situation.

D  They have high power distance communications styles and were fearful of speaking disrespectfully to people they saw as their superiors (air traffic controllers) — even when something was drastically wrong. This prevented them from getting the help they needed when the plane was in trouble.
