In English, the "ed" ending can be pronounced in three different ways: /ɪd/, /t/, and /d/. Here are the answers for the exercise based on different pronunciations of the "ed" ending:

1. **C**: tried (pronounced /d/)
2. **A**: cared (pronounced /d/)
3. **C**: stopped (pronounced /t/)
4. **B**: enjoyed (pronounced /d/)
5. **D**: mixed (pronounced /t/)

So, the words with different pronunciations of the "ed" ending from the list are:

- C: tried /d/
- D: opened /d/
- C: stopped /t/
- D: dropped /t/
- A: cared /d/

For the complete exercise, the words that feature distinct pronunciations would likely be:

- 1. C: tried (different /d/ from others)
- 2. D: dropped (different /t/)
- 3. No additional ones based on the pronunciation.
