Option 1 -> While Ozempic does affect blood sugar, this is not the primary mechanism for weight loss.
Option 2 -> Lasting long in the body is a design feature of the drug, not the reason it causes weight loss.
Option 3 -> The passage states "Ozempic works by making food intake infeasible beyond small quantities" and affects "feelings of satiety," directly encouraging reduced eating.
Option 4 -> This contradicts the passage, which clearly indicates the drug limits food intake.
Hence, Option 3 -> The passage explicitly explains that Ozempic achieves weight loss by making it difficult to eat beyond small quantities and by affecting satiety (fullness) feelings, which naturally encourages minimised eating -> correct
