Solution

The correct option is A emphysema
Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the air sacs in the lungs (alveoli) are damaged.
Alpha-1 antitrypsin is an enzyme produced by the liver that inhibits the action of other enzymes called proteases. Proteases break down proteins as part of normal tissue repair. Alpha-1 antitrypsin protects the lungs from the damaging effects of proteases.
Genes that code for important proteins are introduced into animals to produce particular products to treat certain diseases.
e.g: α-I antitrypsin is extracted from transgenic sheep and treat emphysema.
