A good business idea should be related to what?

Correct answer: A solution to a need or problem

A business idea becomes meaningful when it identifies a customer need or problem and offers a useful product or service to address it. Such an idea has a better possibility of attracting customers and creating value, although success also requires planning and proper execution. Thus, option A is correct. Working without customers, spending without a plan, or accepting permanent loss does not describe a sound business opportunity.
