Choose from the options lettered A - E the one that has the same consonant sound as the one represented by the underlined letter(s) Keen

Analyze the question: The underlined letter(s) in "Keen" are not shown, but the question is about the consonant sound at the start of the word, the letter K. We need the option whose underlined consonant has the same sound, /k/.

Concept: Letters can be pronounced differently depending on the word:

• "ch" in chin is /tʃ/
• "c" before "o", "a" or "u" is usually the hard /k/ sound
• "kn" at the start of a word has a silent k, so the sound is /n/

Step-by-step solution:

1. Keen starts with the sound /k/ (as in /kiːn/).
2. Check each option: • A. chin → /tʃ/ (not a match) • B. cool → /k/ (match), because "c" before "oo" is a hard /k/ • C. knife → /n/ (k is silent) • D. knight → /n/ (k is silent) • E. knit → /n/ (k is silent)

Answer: The only option that begins with the /k/ sound is cool, so the answer is B.

Tip: In words starting with "kn-", the "k" is silent (knife, knee, know, knock). So if the question is about the /k/ sound, eliminate every "kn" word immediately. Also remember that "c" is hard /k/ before a, o, u (cat, cool, cut) and soft /s/ before e, i, y (city, cent).
