Which of the following reduces the likelihood of receiver desensitization?

Because receiver desensitization is caused by an extremely strong adjacent signal overloading the front-end amplifier stages, the most direct solution is to reduce the strength of the incoming signals before they reach those sensitive components. By turning on an RF attenuator before the first RF stage, you reduce the power of all signals entering the receiver. While this does weaken the desired signal, it drops the overpowering interfering signal out of the saturation range of the front-end amplifier. This restores the amplifier's linear operation and vastly improves the signal-to-noise ratio, making the desired signal readable again. Increasing the receiver's front-end gain is the exact opposite of what you want, as it would cause the receiver to overload even faster. Changing AGC speeds or the IF frequency does not solve the root problem of physical front-end saturation.
