The Correct Answer is C
A cerebral concussion is a mild traumatic brain injury that occurs when a blow to the head causes the brain to move rapidly inside the skull, resulting in temporary changes in brain function. A concussion can cause confusion, memory loss, impaired concentration, dizziness, headache, nausea, blurred vision, and mood changes. Most concussions resolve within a few days or weeks with rest and monitoring.

Explanation
These two conditions belong to the disease classification of chronic obstructive pulmonary disease (COPD). COPD is a group of lung diseases that cause persistent and progressive airflow limitation and difficulty breathing. Asthma is a condition that causes inflammation and narrowing of the airways, leading to wheezing, coughing, chest tightness, and shortness of breath. Pulmonary emphysema is a condition that damages the alveoli (air sacs) in the lungs, reducing their elasticity and surface area, resulting in less oxygen exchange and more trapped air. Both asthma and pulmonary emphysema can be triggered by environmental factors, such as allergens, pollutants, tobacco smoke, or infections. The main difference between asthma and pulmonary emphysema is that asthma is reversible with medication, while pulmonary emphysema is irreversible and progressive.
