Option (B) is the correct answer because it is the FALSE statement. A business plan IS usually required when obtaining finance for a startup. Investors, banks, and other financial institutions typically demand a comprehensive business plan before providing funding to assess the viability and potential of the business. Statement (A) is true as existing companies do prepare business plans to manage growth effectively. Statement (C) is also true as a well-prepared business plan helps entrepreneurs identify potential pitfalls and avoid costly mistakes. Since only statement (B) is false, option (D) 'All of the above' is incorrect.
