Which New Town was created after World War Two?

The choice of Milton Keynes is correct because it was specifically established as a New Town following World War Two, founded in 1967 to accommodate the post-war population growth and to alleviate housing shortages in London and the surrounding areas. Milton Keynes was designed to provide planned communities with ample green spaces, efficient transportation systems, and a mix of residential, commercial, and recreational facilities.

In contrast, the other locations mentioned, such as Luton, Brentwood, and Watford, did not emerge as official New Towns after the war. Instead, they were already established towns or cities that grew organically over time. Luton has a historical background as an industrial town, while Brentwood and Watford developed as residential and market towns in the preceding centuries, with their growth significantly influenced by proximity to London rather than the specific strategic planning seen in Milton Keynes.
