**Core Concept**
Inguinal hernias are protrusions of abdominal contents through the inguinal canal, and understanding their classification, presentation, and treatment is crucial in clinical practice. The question tests knowledge of hernia types, their management, and anatomical landmarks.

**Why the Correct Answer is Right**
* **Option A:** In children, indirect inguinal hernias are often treated surgically due to the high risk of incarceration and strangulation. Medical management is not typically recommended as a primary treatment.
* **Option B:** In Richter's hernia, only a portion of the intestinal wall is incarcerated, often leading to segmental ischemia and infarction. Absolute constipation is not a characteristic feature of Richter's hernia.
* **Option C:** Indirect inguinal hernias are the most common type of hernia in adults, accounting for approximately 70-90% of cases.
* **Option D:** The deep inguinal ring is actually a slit-like opening in the transversalis fascia, located lateral and above the mid-point of the pubic tubercle, not above the entire pubic tubercle.

**Clinical Pearl / High-Yield Fact**
When examining a patient with a suspected inguinal hernia, it's essential to note the location of the hernia (indirect or direct), the presence of any symptoms like pain or nausea, and to perform a thorough physical examination to assess for signs of incarceration or strangulation.

**Correct Answer: C. Indirect inguinal hernia is the MC type**
