Final answer:
The correct answer is option B. Bootstrapping is the entrepreneurial approach of starting a business with minimal resources, focusing on cost-effectiveness and personal finances rather than outside funding.
Step-by-step explanation:
The entrepreneurial focus that is concerned with doing the most work with the fewest resources is known as bootstrapping.
Bootstrapping refers to a situation where an entrepreneur starts a company with little capital, relying on personal finances and the initial cash flow of the company, rather than seeking substantial external investments right away. This approach typically involves being very frugal and finding cost-effective ways to operate the business.
