The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Assertion and Reason:** - Assertion: Triple X females are called super females. - Reason: They often give birth to triplets and quadruplets. 2. **Evaluate the Assertion:** - Triple X syndrome (or trisomy X) occurs when a female has three X chromosomes instead of the typical two. This condition is indeed referred to as "super females." Therefore, the assertion is **true**. 3. **Evaluate the Reason:** - The reason states that triple X females often give birth to triplets and quadruplets. However, the occurrence of triplets and quadruplets is not directly related to the number of X chromosomes. The production of multiple births (triplets or quadruplets) can occur due to various factors such as the release of multiple eggs or the splitting of embryos, but it is not a characteristic feature of triple X syndrome. Therefore, the reason is **false**. 4. **Conclusion:** - Since the assertion is true and the reason is false, the correct answer is that the assertion is true and the reason is false. **Final Answer:** - Assertion is true, Reason is false. ---
