Answer

**Step-by-Step Solution:**

1. **Understand the Menstrual Cycle Stages**: The menstrual cycle consists of several phases: menstruation, follicular phase, ovulation, and luteal phase. Each phase has distinct hormonal changes.

2. **Identify Key Hormones**: The two key hormones involved in the menstrual cycle are Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH). These hormones are crucial for regulating the reproductive process.

3. **Observe Hormonal Changes**: During the follicular phase, both LH and FSH start to increase as the body prepares for ovulation. This phase is characterized by the maturation of ovarian follicles.

4. **Locate the Peak Levels**: The peak levels of LH and FSH occur just before ovulation. This surge is often referred to as the "LH surge."

5. **Determine the Timing of the Surge**: The LH and FSH surge typically occurs around the 14th day of the menstrual cycle, which is when ovulation takes place.

6. **Conclude the Answer**: Based on the information gathered, the correct answer to the question is that both LH and FSH attain peak levels on the 14th day of the menstrual cycle.

**Final Answer**: The correct answer is option A: 14th day.
