Respuesta :
The best answer seems to be C because the sentence is hesitating on what to say. I'm so... Happy? upset? Hope this... helps! Get it?
Answer:
C -I am so . . . happy to see you here today.
Explanation:
"I am so..."
The speaker stops right there. As if the speaker is unsure of what to say next. In neither other option there's such a stop. The speaker stops right after saying the one thing that determines what he or she is feeling. The perfect definition. "I am so..." What? Sad? Annoyed? Disgusted? "...happy".
