Infrared countermeasures used by aircraft to counter infrared-guided missiles are called?

Explanation:
Infrared countermeasures use decoys that emit a strong infrared signature to lure heat-seeking missiles away from the aircraft. Flares are bright, hot decoys ejected from the aircraft; their intense infrared output makes them appear as the hottest target, so the missile seeker steers toward the flare instead of the airplane. That’s why flares are the standard answer for countering infrared-guided missiles. The other options don’t fit: chaff is used to confuse radar by creating false reflections, Doppler range gates are radar signal processing techniques, and sonobuoys are for submarine detection—not air-based infrared protection.
