**Core Concept**
The question is testing the knowledge of recurrence and metastasis patterns in gynecological malignancies, specifically in the context of pelvic surgery. This requires an understanding of the anatomical pathways and sites where these cancers are likely to recur or metastasize.

**Why the Correct Answer is Right**
The correct answer, **B. Carcinoma ovary -- Lung**, is incorrect because ovarian cancer typically metastasizes to the peritoneal surfaces, including the liver, spleen, and peritoneal cavity, rather than the lungs. The peritoneal spread is due to the direct seeding of cancer cells from the primary site into the peritoneal cavity. The lungs are not a common site for metastasis in ovarian cancer.

**Why Each Wrong Option is Incorrect**
**Option A:** Carcinoma cervix -- Lateral pelvic wall and central pelvis is incorrect because while the lateral pelvic wall and central pelvis are indeed common sites for recurrence in cervical cancer, the question is looking for the least common or incorrect site. However, the statement is not entirely wrong, as it is a valid site for recurrence.

**Option C:** Chorionepithelioma - Suburethral anterior vaginal wall is incorrect because chorionepithelioma (gestational trophoblastic disease) typically metastasizes to the lungs, brain, and other sites, but not specifically to the suburethral anterior vaginal wall.

**Option D:** Carcinoma body --Vault of vagina is incorrect because the vault of the vagina is a common site for recurrence in cervical cancer, especially after radical hysterectomy.

**Clinical Pearl / High-Yield Fact**
In pelvic surgery for gynecological malignancies, it's essential to be aware of the common sites for recurrence and metastasis to plan appropriate follow-up and treatment strategies.

**✓ Correct Answer: B. Carcinoma ovary -- Lung**
