Which of the following receiver circuits can be effective in eliminating interference from strong out-of-band signals?

Strong out-of-band signals can overload a receiver's first amplifier or mixer, causing issues like desensitization, intermodulation, or blocking. To prevent this, you must attenuate the unwanted signals before they ever reach the active components. A front-end filter or preselector is placed at the very beginning of the receiver chain, directly after the antenna. It allows only the desired band of frequencies to pass through while blocking strong signals from other bands, effectively protecting the receiver's front end from overload. While narrow IF filters and notch filters are excellent for removing interference, they are located further down the receiver chain. By the time a signal reaches an IF filter, a strong out-of-band signal has already overloaded the front end.
