Which set represents the classic symptoms of diabetes insipidus?

Explanation:
Diabetes insipidus causes the kidneys to pass large volumes of dilute urine because water reabsorption is impaired. As a result, you see diuresis (increased urination). The substantial fluid loss can lead to intravascular dehydration, so the heart compensates by beating faster (tachycardia) and the patient often feels weak or fatigued. This combination—very high urine output with signs of dehydration like tachycardia and weakness—best represents the classic symptoms of diabetes insipidus. Other options mix symptoms that are not characteristic of DI. They either reflect urinary leakage from another mechanism, fluid overload, GI symptoms, or non-renal issues, rather than the dehydration-driven triad seen with DI.
