**Core Concept**
Uterovaginal prolapse is a condition where the uterus and/or vagina loses its normal anatomical position, often due to weakened pelvic floor muscles or connective tissue. Management of uterovaginal prolapse depends on the severity, symptoms, and patient's preferences, including surgical or non-surgical interventions.

**Why the Correct Answer is Right**
A rubber ring pessary is a non-surgical, removable device used to support the uterus and/or vagina, alleviating symptoms of prolapse such as pelvic pressure and urinary incontinence. The ring pessary works by providing physical support to the prolapsed organs, thereby preventing further descent and reducing discomfort.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because a rubber ring pessary is not suitable for women with significant prolapse who require more substantial support or have other underlying pelvic floor abnormalities.
**Option B:** This option is incorrect because a rubber ring pessary is not a definitive treatment for uterovaginal prolapse; it is a temporary solution to manage symptoms.
**Option C:** This option is incorrect because a rubber ring pessary is not a surgical intervention; it does not address the underlying cause of prolapse.

**Clinical Pearl / High-Yield Fact**
A rubber ring pessary is a useful option for women who are not good surgical candidates, have significant comorbidities, or prefer a non-surgical approach to managing uterovaginal prolapse.

**Correct Answer: C. A rubber ring pessary is an appropriate management for a woman who is having utero-vaginal prolapse.**
