- A. Wet Processing
- B. Natural Processing ✓
- C. Honey Processing
- D. Washed Processing
Why: Natural processing is also known as the 'dry method' because the coffee cherries are dried with the fruit still intact, which requires less water and is often used in regions with limited water access.

- A. Natural Processing
- B. Wet Processing ✓
- C. Honey Processing
- D. Sun Dried Processing
Why: In wet processing, after the coffee cherries are pulped and the mucilage is removed, the beans are fermented in water and then washed and dried, resulting in a clean and bright flavor profile.

- A. Wet Processing
- B. Natural Processing ✓
- C. Honey Processing
- D. Washed Processing
