Answer 1

At subsonic speeds propellor engine are a decent bit more efficient than jet engines.

For large transport aircraft, efficiency is often times more important than being able to reach high trans sonic speeds, so propellors are a popular choice.

And as in the case of the A400M, the props can be used in counter rotating pairs, cancelling out prop torque and improving the handling of the aircraft
