Hi everyone.

As explained in the reference link :

To calculate the SNR value, we add the Signal Value (RSSI) to the Noise Value and it generates (or should) a positive number that is expressed in decibels (db). For example, lets say your Signal value is -55dBm and your Noise value is -95dBm.

-55dBm + -95dBm = 40db this means you have an SNR of 40, the general rule of thumb is that any SNR above 20 is good.

So answer is B & D
