This is because there is a chlorine atom (Cl) attached to the beta carbon (the carbon next to the carboxylic acid group) of a butyric acid (four carbon) chain. Choice A (λ-chlorobutanoic acid) is incorrect because it indicates a three-carbon chain instead of a four-carbon chain. Choice B (β-chlorobutanoic acid) is incorrect because it indicates a carboxylic acid group on the third carbon instead of the fourth carbon. Choice D (λ-chlorobutyric acid) is incorrect because it indicates a three-carbon chain. Choice E (3-chlorobutyric acid) is incorrect because it does not specify which carbon the chlorine is attached to.
