The Correct Option is B

Solution and Explanation

The clinical presentation and MRI findings, including T1 hyperintensity and T2 hypointensity with dark shading, are characteristic of an endometrioma, also known as a "chocolate cyst." This condition is caused by the presence of endometrial tissue in the ovaries, often associated with dysmenorrhea and infertility.
