The correct answer is B ASSERTED. We can eliminate commented and murmured because they imply the woman is somewhat timid about what she saying, and the previous word forcefully tells us this is not the case. We can eliminate snarled because it implies anger. The only choice left is ASSERTED because it means to claim, declare, contend etc
I believe it's B as well if not then it is D
The action verb is glide :)
