In the book of Revelation, what is the theological significance of the 'mark of the beast' (666) in relation to the themes of idolatry and spiritual compromise?

A It is primarily a literal mark that will physically identify those who are not saved during the end times. B It symbolizes the subtle and pervasive ways in which worldly power and idolatry can corrupt believers, leading them to compromise their faith and allegiance to God. C It represents a specific political system that will emerge in the last days to persecute Christians. D It is a metaphor for economic inequality and the exploitation of the poor by the wealthy.
