The correct answer is

One

To solve this logical reasoning question, we need to analyze the given sequence of letters: Q K Q N X K G G V M L A W T W K N G V. The task is to find how many consonants are immediately preceded by a vowel and also immediately followed by a consonant. Let's break down the steps to find the solution:

  1. Identify the vowels and consonants. The vowels in English are A, E, I, O, U. Therefore, all other letters in the series are consonants.
  2. Start from the left and move to the right in the given sequence. Look for the pattern "vowel-consonant-consonant."
  3. Analyze the sequence step-by-step:
  • Q: Consonant, not preceded by a vowel.
  • K: Consonant, preceded by a consonant (Q).
  • Q: Consonant, preceded by a consonant (K).
  • N: Consonant, preceded by a consonant (Q).
  • X: Consonant, preceded by a consonant (N).
  • K: Consonant, preceded by a consonant (X).
  • G: Consonant, preceded by a consonant (K).
  • G: Consonant, preceded by a consonant (G).
  • V: Consonant, preceded by a consonant (G).
  • M: Consonant, preceded by a consonant (V).
  • L: Consonant, preceded by a consonant (M).
  • A: Vowel, preceded by a consonant (L).
  • W: Consonant, preceded by a vowel (A), and followed by T (consonant). This matches our pattern.
  • T: Consonant, preceded by a consonant (W).
  • W: Consonant, preceded by a consonant (T).
  • K: Consonant, preceded by a consonant (W).
  • N: Consonant, preceded by a consonant (K).
  • G: Consonant, preceded by a consonant (N).
  • V: Consonant, preceded by a consonant (G).
  1. After evaluating each character, we found that only the sequence "A W T" matches the pattern "vowel-consonant-consonant."
  2. Thus, there is one consonant (W) that is immediately preceded by a vowel (A) and also immediately followed by a consonant (T).

Therefore, the correct answer is: One.
