The answer is Busy. because Busy describes the current happening? I guess.
C) Tying the paragraph together is definitely one of them. If I had to choose another one I would include B) Emphasizing the important points.
a noun

You should never avoid your listiners they might have something important to say that could go along with he or shes evidence you don't know what your talking about
A words connotation is complied of the use of the word and its definition. The correct answer here is C. Dust.
Dust is dirty and most oftentimes a nuisance, this gives it the strongest negativity of the word provided. The action of eating is a neutrally connotated word, as it is a regular habit needed for survival. Hands are neutral as there are seemingly just a part of the body. Lastly, sweets are seen as delicious and pleasurable, which gives it a positive connotation. So, the only negative word here is dust.
I hope this helps :)
