The Spitfire originated from a racing plane.

The answer is false, not true. The Spitfire did not originate from a racing plane. The design of the Spitfire was not based on a racing aircraft, but rather on the Supermarine S.6B, a seaplane that won the Schneider Trophy in 1931. The S.6B was an advanced aircraft for its time and its design heavily influenced the development of the Spitfire. However, the Spitfire was specifically designed as a high-performance fighter aircraft, not a racing plane.
