For example, all halogens(fluorine,chlorine, bromine,iodine) are active or reactive as they react easily to achieve nearest noble gas configuration. Being active or reactive is a comparable term. So if you are asked which one is reactive, just analyze it's electronic configuration, who knows , it might give you a hint. read more
