**Core Concept**
The patient's presentation with amenorrhea (absence of menses), raised serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and low serum estradiol levels points towards a disorder of the hypothalamic-pituitary-gonadal axis. This condition is characterized by anovulation, which is a failure of the ovaries to produce eggs for ovulation.

**Why the Correct Answer is Right**
The patient's raised LH and FSH levels indicate hypergonadotropic hypogonadism, which is a condition where the ovaries are not responding to the pituitary hormones. This is often seen in cases of premature ovarian failure (POF) or premature ovarian insufficiency (POI). However, in this case, the patient is 36 years old, which is relatively young for POF/POI. The low serum estradiol levels further support this diagnosis. The negative pregnancy test rules out pregnancy as a cause of amenorrhea.

**Option D:** This option is not provided.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that anovulation can occur due to a variety of factors, including hypothalamic, pituitary, and ovarian causes. The patient's age and presentation should guide the clinician to investigate further for the underlying cause.
