D. combination of FSH and LH

Answer

**Step-by-Step Solution:**

1. **Understanding Menstruation:** Menstruation is a part of the menstrual cycle in females, which involves the shedding of the uterine lining when there is no fertilization of an egg.

2. **Identifying the Question:** The question asks how menstruation can be deferred or delayed in human females.

3. **Role of Hormones:** The menstrual cycle is regulated by various hormones, primarily estrogen and progesterone. These hormones play a crucial role in the ovulation process.

4. **Combination of Estrogen and Progesterone:** The administration of a combination of estrogen and progesterone can prevent ovulation. When ovulation is prevented, menstruation does not occur, effectively deferring the menstrual cycle.

5. **Other Hormones:** Other hormones like FSH (Follicle-Stimulating Hormone) and LH (Luteinizing Hormone) promote ovulation. If these hormones are administered, they would not defer menstruation but rather encourage it.

6. **Conclusion:** Therefore, the correct answer to the question is that menstruation can be deferred by the administration of a combination of estrogen and progesterone.

**Final Answer:** Menstruation can be deferred by the administration of a combination of estrogen and progesterone.
