The correct answer is D.
OBJ-4.6: An open license or free license is the legal statement that allows free content and free software to be free. Since the customer doesn’t want to pay for a license, the user must get a word processing program that uses an open license to not pay for their software. For example, OpenOffice is an open license-based software that provides a word processor that can be used on Windows, Linux, or OS X for free. A Personal license is an option for private individuals who purchase a license with their own funds and solely for their own use. Personal licenses are not to be purchased, refunded, or in any way financed by companies. A business license is the standard licensing option for organizations and business entities. With Microsoft, a company can purchase anywhere from 1 to 300 user licenses under the business license program. An enterprise license is like a business license, but for an unlimited number of users and is designed for large corporate and government networks.
