Practice question

Correct option is C, Direct delivery without dilution. In Endocrinology, the accurate description is Direct delivery without dilution, and that is what you should commit to memory. Keep the definition tight and the role clear — Direct delivery without dilution is the option that correctly names the structure, process, or principle asked for in Endocrinology. Then Direct delivery without dilution is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Direct delivery without dilution.
