Best Answer Explained in Below-:

The correct noun form of 'universal' is 'universality' (option D). To understand why, we can break down the term and its construction. 'Universal' is an adjective that describes something applicable to all cases or instances. The noun form typically refers to the quality or state of being universal.

Among the options, 'universality' specifically captures this concept of universality—an abstract notion that reflects the character or condition of being universal. This noun is derived from the Latin root 'universalis,' which means 'of the whole' or 'pertaining to all.'

In contrast, the other options are either incorrect or nonstandard. 'Universalty' (A) is a misspelling and not recognized in standard English. 'University' (B) refers to an institution of higher education, which is unrelated to the concept of universality. 'Universiality' (C) contains a spelling error, as it adds an unnecessary 'i.'

Thus, 'universality' is the only option that accurately conveys the intended meaning and aligns with English language conventions, making option D the correct choice.
