Verified step by step guidance

1. Step 1: Understand the definitions and terms provided. The first definition is 'Having a hoarse voice.' The term that matches this is 'dysphonia,' which refers to difficulty or discomfort in speaking, often resulting in a hoarse voice.
2. Step 2: For the second definition, 'Medical device used to measure lung capacity,' identify the term that fits this description. A 'spirometer' is a device used to measure the volume of air inhaled and exhaled by the lungs, so this matches the definition.
3. Step 3: The third definition is 'Presence of air in the chest cavity.' The medical term for this condition is 'pneumothorax,' which occurs when air leaks into the space between the lung and chest wall, causing the lung to collapse.
4. Step 4: Match each definition with the correct term based on the above understanding: 1) Having a hoarse voice = dysphonia (c), 2) Medical device used to measure lung capacity = spirometer (a), 3) Presence of air in the chest cavity = pneumothorax (d).
5. Step 5: Review the options provided and select the one that corresponds to the matches: 1) c, 2) a, 3) d.
