**Core Concept**
The question is testing the management of an inguinal mass in a neonate, specifically the condition known as **inguinal hernia**, which is a protrusion of abdominal contents through a weak point in the abdominal wall. Inguinal hernias are common in infants and can be either congenital or acquired.

**Why the Correct Answer is Right**
The management of inguinal hernias in infants involves elective surgical repair, usually performed under general anesthesia. The procedure, known as **Herniotomy**, involves closing the hernial sac and repairing the weakened area in the abdominal wall. This is usually done by a pediatric surgeon.

**Why Each Wrong Option is Incorrect**
**Option A:** Immediate surgical repair is not recommended for all inguinal hernias in infants. In many cases, a watchful waiting approach is adopted, with surgery scheduled if the hernia persists or causes symptoms.

**Option B:** Laparoscopic repair is not typically recommended for inguinal hernias in infants due to the small size of the hernia and the risk of complications.

**Option C:** Conservative management with pain relief and monitoring is not sufficient for inguinal hernias, as it does not address the underlying anatomical defect.

**Option D:** Delaying surgery until the child is older is not recommended, as it increases the risk of complications and strangulation of the hernia.

**Clinical Pearl / High-Yield Fact**
Infants with inguinal hernias may present with a reducible bulge in the groin, but some may have a non-reducible bulge or even signs of bowel obstruction. A high index of suspicion and prompt referral to a pediatric surgeon are essential in managing these cases.

**Correct Answer:** C.
