Following Factors are essential for judging the adequacy of market for proposed business idea.
A. Demand in Domestic Market
B. Competitors and their market share
C. Demand in Export Market
D. Treasury bond yields
E. Customer tastes and preferences
Choose the correct answer from the options given below:

To assess the adequacy of the market for a business, demand in domestic and international markets, competition analysis, and customer taste and preference analysis are important and directly relevant. But treasury bond yields are a macroeconomic factor used to judge financial markets, not specifically business markets, unless investor funding is directly taken into account.

For example, setting up a sugar-free ice cream startup would not directly consider bond yields when assessing the ice cream market landscape.
