The correct word that should fill the blank in the phrase 'All we like sheep have ______ astray' is A) Wandered. This phrase is a biblical allusion referencing a passage from Isaiah 53:6, which speaks to the tendency of people to go their own way, rather than following a righteous path. It's a common metaphor used to describe going away from what is considered the correct or moral route.
