How can a specification document function as a legal document?

by clarifying the scope of work agreed to by

developers and clients

by providing quotes of market research

statistics

by analyzing the competitive marketplace

O by documenting the number of bugs logged

by software testers

by clarifying the scope of work agreed to by

developers and clients

Explanation:

Market research statistics have nothing to do with the legal issues, and the same thing applies to the competitive analysis. No one will complain from outside if you earn less, and even if you earn more pertaining that you pay off their cast-offs. However, in the scope of this question, the second and third options cannot be considered as the specification documentation as a legal document. Also, the number of bugs logged by software testers is going to be acknowledged fully by the end of the project, and hence the fourth option is also not a legal document. However, the first option and that is by clarifying the scope of work agreed to by developers and clients is certainly a legal document, as developers and clients will be questioned on this basis in the coming future, and till the project finalized. And hence, the first option is the correct option.
