The word 'pious' means :

Right Answer: religious and moral

The adjective 'pious' is used for a person who is deeply devoted to religion and follows moral and virtuous conduct in daily life. It carries a positive sense of reverence, devotion and righteousness, as in a pious woman or a pious deed. The other choices are unrelated in meaning: 'worthless' means having no value, 'liberal' means generous or open minded and tolerant of other views, and 'traitor' means a person who betrays his own country or friends. Hence 'religious and moral' correctly explains the word pious.
