**Core Concept**
The superficial palmar arch is a vital artery that supplies blood to the palmar surface of the hand. It is formed by the ulnar artery, which contributes the majority of the arch, and the radial artery, which contributes a smaller part.

**Why the Correct Answer is Right**
The superficial palmar arch begins at the level of the lateral part of the 2nd metacarpal bone, where the ulnar artery contributes to the formation of the arch. The ulnar artery brings the majority of blood supply to the arch through its deep palmar branch. The radial artery contributes a smaller part to the arch through its superficial palmar branch. The arch is formed in such a way that it provides a rich network of blood vessels to the palmar surface of the hand.
