Choose the option that has the same vowel sound as the one represented by the letter(s) underlined. Mother

The word "mother" has the vowel sound represented by the letter "o." This sound is the /ʌ/ sound, which is a short, mid-central, and unrounded vowel. In the context of American English and many dialects of British English, this sound can be found in other words as well. Let's break this down:

1. Verb: The word "verb" does not have the /ʌ/ sound. It has a vowel sound similar to /ɜː/ or /ɜr/ in some dialects. Hence, it does not match the sound in "mother."

2. Mercy: The vowel sound in "mercy" is typically pronounced as /ɜː/ or /ɜr/, which differs from the /ʌ/ sound in "mother."

3. About: "About" contains the /ə/ sound, especially in the first syllable, which is closer to a schwa sound. The vowel sounds in "about" do not match the /ʌ/ sound in "mother."

4. Jump: In "jump," the vowel sound is the same /ʌ/ sound as in "mother." It is the same short, mid-central, unrounded vowel.

Therefore, the word "jump" shares the same vowel sound with "mother."
