Quizplus · Accepted Answer

A LIA slant contains lysine as a source of amino acid, glucose as a source of carbohydrate, ferric ammonium citrate as an indicator of hydrogen sulfide production, and sodium thiosulfate as a source of sulfur. The other choices (A, C, and D) are incorrect as they contain different combinations of components that are not present in a LIA slant.
