To solve this problem, we need to identify the conditions in urine that are indicative of Diabetes Mellitus. Let's analyze each option:$\newline \bullet$Option 1: Uremia and Renal Calculi$\newline$ - Uremia refers to the presence of excessive urea in the blood, not urine, and is related to kidney failure.$\newline$ - Renal calculi, or kidney stones, are not directly related to Diabetes Mellitus.$\newline$ - Therefore, this option is not indicative of Diabetes Mellitus.$\newline \bullet$Option 2: Ketonuria and Glycosuria$\newline$ - Ketonuria is the presence of ketone bodies in the urine, which occurs when the body breaks down fat for energy, a common occurrence in uncontrolled diabetes.$\newline$ - Glycosuria is the presence of glucose in the urine, which happens when blood glucose levels are high, exceeding the renal threshold, a hallmark of Diabetes Mellitus.$\newline$ - Therefore, this option is indicative of Diabetes Mellitus.$\newline \bullet$Option 3: Renal calculi and Hyperglycaemia$\newline$ - Renal calculi are not directly related to Diabetes Mellitus.$\newline$ - Hyperglycaemia refers to high blood glucose levels, not a condition in urine.$\newline$ - Therefore, this option is not indicative of Diabetes Mellitus.$\newline \bullet$Option 4: Uremia and Ketonuria$\newline$ - Uremia is related to kidney failure, not Diabetes Mellitus.$\newline$ - While ketonuria is related to Diabetes Mellitus, the presence of uremia makes this option incorrect.$\newline$Based on the analysis, the correct option is:$\newline$Option 2: Ketonuria and Glycosuria
