Answer :

The noun Sky is not an abstract noun.

An abstract noun is a noun form in which the material form is not tangible, it is not in the form of a substance.

Therefore Truth is abstract, so is Beauty and Faith.

But Sky is not an abstract noun.  It has a material form.

So option B is the correct one.
