The correct answer is "letter c. malingering."
Malingering is described as falsifying symptoms of mental or physical well-being of a person to achieve a certain goal, an example is that malingering a certain mental illness or physical illness may be used as a mitigating factor to reduce the sentence of a criminal or to receive special treatment in prison. It may also be used to skip school or work in the military.
