D. Ovulation occurs under a high titre of LH.

Answer

To determine which statement is false, we will analyze each option provided in the question step by step.

### Step 1: Analyze the First Statement
The first statement is about Menarche, which is defined as the beginning of menstruation. This statement is true because Menarche marks the onset of the menstrual cycle in females, typically occurring during puberty.

**Hint:** Remember that Menarche signifies the start of a female's reproductive capability.

### Step 2: Analyze the Second Statement
The second statement discusses the shedding of the endometrial lining. This is also true. The endometrium prepares itself each month to potentially nourish a fertilized embryo. If fertilization does not occur, the lining is shed during menstruation.

**Hint:** The endometrial lining is crucial for implantation; its shedding is a normal part of the menstrual cycle.

### Step 3: Analyze the Third Statement
The third statement claims that menopause occurs at the beginning of puberty. This statement is false. Menopause is the cessation of menstruation and fertility, typically occurring in women around the age of 52. Puberty is when Menarche occurs, not menopause.

**Hint:** Menopause signifies the end of a woman's reproductive years, while puberty marks the beginning.

### Step 4: Analyze the Fourth Statement
The fourth statement mentions that ovulation occurs under high levels of luteinizing hormone (LH). This statement is true. Ovulation is triggered by a surge in LH, which leads to the release of a mature egg from the ovaries.

**Hint:** LH plays a critical role in the menstrual cycle, especially in triggering ovulation.

### Conclusion
After analyzing all the statements, the false statement is the third one, which incorrectly states that menopause occurs at the beginning of puberty.

**Final Answer:** The false statement is the third one: "Menopause occurring at the beginning of puberty."
