Epithelial surface tumor is the "classical" ovarian adenocarcinoma subtype & it is malignant, of course. Metastatic tumors are malignant by definition, whilst Krukenberg tumor is a special form of tumor metastatic to the ovary, deriving from the stomach (signet-ring cells are characteristic), and rarely from other GI locations or even the breast.

Germ cell tumors (eg dysgerminoma) are malignant tumors & are expected in younger populations of women, rather than postmenopausal women.

What is more, the macroscopic image of this tumor reveals a solid tumor, consisting of fibrous, pale-yellow tissue.

According to the above, I would chose D - stromal cell tumor, and more specifically thecoma (in order to differentiate it from granulosa cell tumor, which is also a stromal cell tumor, with a probability of 20% to be malignant, microscopically characterized by the so-called Call-Exner bodies).

I agree that's a stromal tumor, answer (D), but I believe it's a Brenner tumor. The exact same picture is on Wikipedia under Brenner tumor.
