**Core Concept**
A wandering spleen is a rare congenital anomaly where the spleen loses its normal attachments to surrounding structures, allowing it to move freely within the abdominal cavity. This condition often results from the incomplete development of the splenorenal ligament and the gastrosplenic ligament. The spleen's mobility can cause various complications, including torsion and infarction.

**Why the Correct Answer is Right**
The correct answer is related to the anatomical and embryological basis of a wandering spleen. The absence of normal splenic attachments leads to the spleen's mobility, which can cause complications such as torsion and infarction. The splenorenal ligament and gastrosplenic ligament play crucial roles in maintaining the spleen's position. In a wandering spleen, these ligaments are either underdeveloped or absent, allowing the spleen to move freely.

**Why Each Wrong Option is Incorrect**
**Option A:** This option might be a true statement regarding wandering spleen, as it is indeed a rare congenital anomaly. However, it does not directly address what is false regarding wandering spleen.

**Option B:** This option might be a true statement regarding wandering spleen, as it is indeed associated with various complications, including torsion and infarction.

**Option C:** This option might be a true statement regarding wandering spleen, as it is indeed related to the incomplete development of the splenorenal ligament and the gastrosplenic ligament.

**Option D:** This option might be a false statement regarding wandering spleen, but without the correct answer, it is difficult to determine.

**Clinical Pearl / High-Yield Fact**
A key aspect of a wandering spleen is its potential to cause torsion and infarction due to its mobility. It is essential to recognize this condition and its associated complications to provide prompt and effective treatment.

**Correct Answer: D.**
