Assertion: Pregnant women may show some presence of glucose in their postprandial urine although they have no diabetes.
Reason: In pregnant women the glomerular filtration rate is slightly increased. As a result the tubular load of glucose exceeds the tubular maximum for glucose reabsorption.

Options

A. Both the statement are true
B. Both the statement are false
C. Statement I is true and Statement II is false
D. Statement I is true and Statement II is true

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that pregnant women may show some presence of glucose in their postprandial urine even if they do not have diabetes. This is an important observation as it indicates that glucose can appear in urine under certain physiological conditions.

2. **Understanding the Reason:**
- The reason provided explains that during pregnancy, the glomerular filtration rate (GFR) is slightly increased. This means that the kidneys filter blood more efficiently, leading to a higher volume of fluid being processed.

3. **Linking Assertion and Reason:**
- The increased GFR results in a higher tubular load of glucose. The kidneys have a maximum capacity (tubular maximum) to reabsorb glucose in the proximal convoluted tubule (PCT). If the amount of glucose filtered exceeds this maximum, some glucose will remain in the urine.

4. **Conclusion:**
- Since both the assertion and the reason are true and the reason correctly explains the assertion, we conclude that both statements are true.

5. **Final Answer:**
- The correct option is that both the assertion and reason are true.
