For RF amplifier its not so much that is "selects" the desired frequency but more so that it improve the SNR of the desired signal more than the surrounding noise. Selecting a desired frequency is more often done by band pass filters which allow only a specific range of frequencies and tunes out the frequencies that are outside of the desired range.
Great explaination Ever🙏👍

Miss, Why do we need to convert the received RF signal to IF signal?
We need to convert ti to fixed IF (such fixed 10,7 MHz or 455 kHz) because it would be a lot of undesired harmonics when tuning the scale on VHF from 87,5-108 MHz through many amplifying transformers and when amplifying this range frequency through transformers for amplifying and selectivity, there would be a lot of undesired harmonics on each different frequency tuned, that is why you convert it to fixed intermediate frequency (IF) and then you work on it for selectivity, limiting, amplifying, demodulating.
Mr.@@vjekoslavcvetnic7500 Thank you so much 🌻💕
