Step 1: Understanding the Question:
The objective of this question is to identify the correct spelling of the word meaning noisy, confused, or disorderly.
This is a vocabulary and spelling-based question designed to test the candidate's familiarity with complex English adjectives.
Step 2: Detailed Explanation:
1. The word in question is an adjective derived from the noun ``tumult''.
2. The noun ``tumult'' refers to a loud, confused noise, especially one caused by a large mass of people, or a state of confusion or disorder.
3. To convert the noun ``tumult'' into its adjective form, we add the suffix ``-ous''. However, because of its Latin origin (``tumultuosus''), an extra vowel ``u'' is retained before the suffix.
4. Therefore, the correct spelling is ``tumultuous'', which consists of the letters: T-U-M-U-L-T-U-O-U-S.
5. Let us analyze the spelling options provided:
- Option (A) ``Tumultous'' is a common misspelling where the first ``u'' after the letter ``t'' is omitted. This is incorrect.
- Option (B) ``Tumultuos'' is incorrect because it lacks the final letter ``u'' in the suffix ``-ous'', ending only in ``-os''.
- Option (C) ``Tumultuous'' is the correct spelling, containing all the necessary vowels in their correct positions.
- Option (D) ``Tumultouss'' is incorrect because it features a double ``s'' at the end, which is non-standard for this adjective.
6. Let us look at some examples of the word in context to better understand its usage:
- ``The stadium erupted in tumultuous applause when the winning goal was scored.''
- ``She had a tumultuous relationship with her business partner, marked by constant arguments.''
7. Recognizing the root word ``tumult'' and the standard Latinate adjective ending ``-uous'' (similar to words like ``continuous'' or ``virtuous'') helps avoid spelling errors.
Step 3: Final Answer:
Therefore, the correct option is (C).
