If the meter is set to read DC voltage in the 20 volt range and it displays a 1 then it should mean 1 volt assuming that the maximum reading would be 20 volts at that setting. But if it is only around 1 volt is might be more accurate to set it at say 2V range to get say 1.6 actual volts.
1. C. you are reusing, because instead of throwing the couch away, you gave it to someone who will "reuse" it.
2. I'm not sure, but I would say B. recycling. Repurposing things that you have no use for limits how much waste there is and how much must be manufactured. This reduces pollution and limits the burden on the environment.
