Here are the words with the underlined parts pronounced differently from the others:

1. **C. question** (The "qu" in question is pronounced /kw/, while the other words have an "o" or "i" sound.)
2. **A. choos** (The "oo" in choos is pronounced /uː/, while the other words have a different vowel sound.)
3. **A. invited** (The "i" in invited has a short vowel sound, while the others have different vowel sounds.)
4. **A. notice** (The "o" in notice is pronounced /oʊ/, while the others have vowel sounds pronounced differently.)
5. **C. oponion** (It appears there may be a typo in "opinion," as it's not a standard English word. However, if you meant "opinion," it must be noted that the "o" in opinion is pronounced /ə/ in unstressed syllables, while the rest have vowel sounds that differ.)
