At a constant true airspeed, which of the following types of drag increases as the aircraft gains altitude?
- Interference drag.
- Parasite drag.
- Induced drag.
Explanation from PART66Online
At a constant true airspeed the air density falls as altitude increases, so the dynamic pressure falls and the lift coefficient must rise to keep lift equal to weight. Induced drag varies inversely with dynamic pressure once the weight is fixed, so it rises with altitude, while parasite drag and interference drag both fall because they vary directly with dynamic pressure.

here the question is: which of the following types of drag increases as the aircraft GAINS altitude?
that means the a/c is ascending with high AoA! induced drag depends upon AoA!
