The Correct Option is B

Solution and Explanation

Concept: Premature ovarian failure, also called primary ovarian insufficiency, occurs before 40 years of age. It is characterized by amenorrhea, elevated FSH and LH, and low ovarian reserve markers such as AMH.

Step 1:
Identify the age and symptom.
The patient is 36 years old and has secondary amenorrhea.

Step 2:
Interpret the hormone levels.
FSH and LH are high: \[ FSH = 36, \quad LH = 56 \] AMH is low: \[ AMH = 0.5 \] This indicates reduced ovarian reserve and ovarian failure.

Step 3:
Choose the diagnosis.
Ovarian failure before 40 years is called: \[ \text{Premature ovarian failure} \] Therefore, the correct answer is Premature ovarian failure.
