To determine the percussion of the chest in patients with Emphysema, we need to follow these steps:

1. Position the patient: Ask the patient to sit upright or slightly lean forward to allow for better access to the chest.

2. Locate the landmarks: Identify the anatomical landmarks on the chest, such as the clavicles, sternum, and ribs. This will help you accurately perform percussion.

3. Choose the percussion technique: There are two main techniques for chest percussion - direct and indirect. In this case, we will focus on indirect percussion.

4. Perform percussion: Use your middle finger or the middle finger of your non-dominant hand to gently tap on the chest wall. Start from the upper chest and move downward, comparing different areas on both sides of the chest.

5. Observe the sound produced: In patients with Emphysema, the percussion sound is typically hyperresonant. This means that the sound produced will be louder and lower in pitch than normal.

6. Compare with other areas: It is important to compare the percussion sound with other areas of the chest to identify any differences. This will help in assessing the extent and distribution of emphysema.

Based on the options provided, the correct answer would be "Hyperresonance" for percussion of the chest in patients with Emphysema.
