All of the decibel weights are designed to apply some type of bias to some frequencies and ignore others.

For instance A is trying to bias frequencies that humans hear and ignore other lower and higher pitches that humans don’t hear because if you don’t hear it it’s not exactly going to factor into the sound level you’re experiencing and therefore the measurement should reflect the “filtering” that you’re hearing range applies.
