Which one of the following sentences contains an abstract noun?

a. his smile could charm anyone.
b. the vase was quite expensive.
c. logic is easily understood.
d. she handed him the dishtowel.

I say its C. Logic is easily understood

The noun in the sentence is "logic" which is abstract since it can't be seen or touched. 

Hope this helps :)

Its c for sure aka logic is easily understood
