I had been asked this question in quiz.

Question is taken from Configuration Layout Considerations topic in chapter Configuration Layout Considerations of Aircraft Design

Answer 1

The correct answer is (a) altering the look angle

Easiest explanation: RCS is based on the look angle. By altering look angle we can alter the rcs of an object. Tail moment arm will affect the stability not the rcs in general. RCS is also reduced by using stealth technology.
