Answer 1

The Shang dynasty is the answer you're looking for as it's also the oldest dynasty on your list.

Ch'in (or Qin) is more known for its ruler who unified the kingdoms of China giving it its name (as well as building the Great Wall). The other two dynasties, the Tang and the Shang, came much afterwards, but by that time, bronze working was already well known.
