Choice C is the best answer because the context makes clear that the kind of “exception” (line 25) Jordan describes should be narrowly constrained, or limited. As lines 26–28 indicate, the Federal Convention of 1787 “limited impeachment to high crimes and misdemeanors, and discounted and opposed the term ‘maladministration,’” presumably because the term implied too broad a scope for the exception.

Choice A is not the best answer because while “channeled” sometimes means “worn,” it would make no sense in context to say that the kind of “exception” (line 25) Jordan describes should be narrowly worn.

Choice B is not the best answer because while “channeled” sometimes means “sent,” it would make no sense in context to say that the kind of “exception” (line 25) Jordan describes should be narrowly sent.

Choice D is not the best answer because while “channeled” sometimes means “siphoned,” it would make no sense in context to say that the kind of “exception” (line 25) Jordan describes should be narrowly siphoned.
