A military aircraft can use _____ as a countermeasure for IR detection

1.	A military aircraft can use _____ as a countermeasure for IR detection.(a) flares(b) lift(c) glares(d) engine temperature increaseI got this question at a job interview.My query is from Configuration Layout Considerations in section Configuration Layout Considerations of Aircraft Design
Answer» The correct option is (a) FLARES The best I can explain: If we increase ENGINE exhaust temperature then, it will increase the IR detection. As a COUNTERMEASURE for IR detection, most of military a/c are using flares. Flares are used to GENERATE fake IR SIGNATURES.
