Concept:The target word with the underlined letter(s) is missing, so the vowel-sound match cannot be determined.
Explanation:To answer correctly, we must first know the vowel sound shown by the underlined letters in the stem word.
Each option has a distinct pronunciation as follows:
A. stir =
/st3:/B. heat =
/hi:t/C. bet =
/bet/D. seed =
/si:d/Without the underlined word, there is no reference vowel sound to compare with these options.
So no option can be logically confirmed as the correct match.
Answer:The question is incomplete because the underlined word is missing.
Therefore, no option, A, B, C, or D, can be selected.
