WHAT IS REFLECTION ?
<u>the throwing back by a body or surface of light, heat, or sound without absorbing it.</u>
I KNOW ABOUT REFLECTION BUT NOT ABOUT MOM REFLECTION
The last one.
Create a bibliography so you can make sure you've cited sources correctly.
I would definitely say B.) A smile because if you were just staring it may be rude or distracting to the speaker and a smile shows you are listening and absorbing the knowledge
It is a adverb clause.
Hope this helps!
