Concept:A word must be chosen that contains the exact sound shown by the phonetic symbol.
Explanation:Read the given phonetic symbol and say its sound aloud.
Pronounce each of the options carefully to see if that sound appears.
The word "pit" does not contain the required sound.
The word "exile" does not contain the required sound either.
The word "serve" is pronounced /sɜːv/ , so its written "r" is silent and gives no matching sound.
The word "regal" is pronounced /ˈriː.ɡəl/ and clearly contains the target sound in its pronunciation.
Thus, "regal" is the correct match for the given phonetic symbol.
Answer:C. regal
