The first necessary condition for a project to be viable is that it should have a market, option A. A project needs to have a potential customer base or target market that is willing to pay for the product or service being offered. Without a market, there would be no demand for the project's output, making it unlikely to succeed. Identifying and assessing the market potential is crucial in determining the viability of a project. While government support, expected return, and reliance on tried and tested technology can be important factors, the presence of a market is typically considered the primary condition for a project's viability.
