For the question, choose the option that has the same consonant sound as the ones represented by the letter(s) underlined.
knot
Answer Details
The underlined letters in knot are kn. In English, when a word begins with "kn," the "k" is silent and only the /n/ sound (voiced alveolar nasal) is pronounced. So "knot" is pronounced /nɒt/, beginning with the same sound as "not."
Now consider each option:
church - begins with /tʃ/ (the "ch" affricate), not /n/.
norm - begins with /n/, the same consonant sound represented by "kn" in "knot."
keep - begins with /k/, which is actually the letter that is silent in "knot."
cease - begins with /s/, not /n/.
The correct answer is norm, because the "n" in "norm" produces the same /n/ sound as the "kn" combination in "knot."
