Concept:The underlined letter in the given word must have the same consonant sound as the word chosen from the options.
Explanation:In “left”, the underlined letter ‘l’ is pronounced with a clear /l/ sound.
Now check each option for the sound of the letter ‘l’.
In “yolk”, the ‘l’ is silent, so it does not match.
In “half”, the ‘l’ is also silent, so it does not match.
In “could”, the ‘l’ is silent as well, so it does not match.
In “bulk”, the ‘l’ is fully pronounced as /l/, just like in “left”.
Therefore, the word that has the same consonant sound is “bulk”.
Answer:B. bulk
