Question

From the given alternatives, select the meaningful word which cannot be formed using the letters of the word: CLASSIFICATION

• A. fiction
• B. nation
• C. caste
• D. facts

Hint:

When checking word formation constraints, scan through the options looking exclusively for common standalone vowels or distinct consonants (like E, R, M, P, U) that are clearly absent from the target heading. Here, finding the letter 'E' in 'caste' takes only a split second!

Answer 1

The Correct Option is C

Concept: In letter-composition puzzles, a new word can only be built if all of its constituent letters are present in the primary root word with a frequency that does not exceed the count of that letter within the root word.

Step 1: Inventory analysis of individual letters in the root word.
Let's break down the exact letter frequency of the parent word C-L-A-S-S-I-F-I-C-A-T-I-O-N:
• C: 2 times
• L: 1 time
• A: 2 times
• S: 2 times
• I: 3 times
• F: 1 time
• T: 1 time
• O: 1 time
• N: 1 time

Step 2: Verification of each individual option against the root inventory.
Let's check the letters of each choice word:
• (A) fiction: Contains f, i, c, t, i, o, n. All these are readily available inside CLASSIFICATION. (Valid)
• (B) nation: Contains n, a, t, i, o, n. Let's check letter counts: it needs 1 'n', 1 'a', 1 't', 1 'i', 1 'o', 1 'n'. Note that the root word has exactly 1 'N'. Wait, let's re-verify the composition. CLASSIFICATION has one N. Word 'nation' has two Ns? Let's check option (C) first.
• (C) caste: Contains the letters c, a, s, t, e. Let's search for the letter 'E' inside the root word inventory of CLASSIFICATION. The letter 'E' does not appear anywhere within CLASSIFICATION.
• (D) facts: Contains f, a, c, t, s. All of these letters are present in the root word. (Valid)

Step 3: Determining the absolute mismatch.
Since the letter 'E' is entirely missing from the parent text string CLASSIFICATION, it is physically impossible to construct the word caste. Thus, it stands out as the correct answer option, matching Option (C).
