**Core Concept**
Meckel's diverticulum is a congenital anomaly of the small intestine, resulting from the incomplete closure of the vitelline duct. It is a remnant of the yolk sac, which connects the embryo to the placenta during fetal development.

**Why the Correct Answer is Right**
Meckel's diverticulum is typically located in the ileum, which is the final portion of the small intestine before the large intestine. The vitelline duct usually closes by the 6th week of gestation, but if it fails to do so, a Meckel's diverticulum forms. This diverticulum is usually found approximately 60 cm from the ileocecal junction, which is the junction between the ileum and the cecum (the first part of the large intestine). The presence of ectopic gastric or pancreatic tissue within the diverticulum can lead to complications such as bleeding or obstruction.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Meckel's diverticulum is not typically located in the jejunum, which is the middle portion of the small intestine. The jejunum is not the usual site of the vitelline duct remnant.
**Option B:** This option is incorrect because Meckel's diverticulum is not usually found in the colon, which is the large intestine. The colon is not a typical site for the vitelline duct remnant.
**Option C:** This option is incorrect because Meckel's diverticulum is not typically located in the stomach. The stomach is not a usual site for the vitelline duct remnant.

**Clinical Pearl / High-Yield Fact**
Meckel's diverticulum can cause complications such as gastrointestinal bleeding, obstruction, or perforation, especially in children. It is essential to consider Meckel's diverticulum in the differential diagnosis of lower gastrointestinal bleeding or abdominal pain in children.

**Correct Answer:** C.
