Explanation:

• Alpha-gal syndrome (AGS) (also called alpha-gal allergy, red meat allergy, or tick bite meat allergy) is a serious, potentially life-threatening allergic reaction. AGS may occur after people eat red meat or are exposed to other products containing alpha-gal.
• The US Food and Drug Administration (FDA) recently approved a first-of-its-kind intentional genomic alteration (IGA) in a line of domestic pigs referred to as GalSafe pigs. It aims to eliminate a type of sugar found in mammals called alpha-gal.

Hence option 1st is correct.
