Answer:
i'm not absolutely certain which one, but it s either A or B I can tell you that.
Explanation:
I think personally think that it would be safe to say that the correct answer is A. It is very common if you walk into a conversation that the people conducting that conversation will be talking with their hands. This alone would be considered "gestures, signs, and signals" and obviously you talking so "words" is definitely there, and people ( I know I do) use "objects" to explain themselves.
