**Core Concept**
Wilm's tumor, also known as nephroblastoma, is a type of cancer that originates in the kidneys. It is the most common type of renal cancer in children.
**Why the Correct Answer is Right**
The commonest presentation of Wilm's tumor is a triad of abdominal pain, abdominal mass, and hematuria. This is due to the tumor's location in the kidney, which can cause a palpable mass to be felt upon physical examination. The tumor can also cause irritation of the surrounding tissues, leading to pain and discomfort. Hematuria, or blood in the urine, can occur due to the tumor's invasion into the collecting system of the kidney.
