Final answer:
A builder may use funds from one project for another project never.
Step-by-step explanation:
A builder may use funds from one project for another project never.
It is generally considered unethical and illegal for a builder to use funds from one project for another project. Each construction project typically has its own allocated funds and budget that should be used solely for that specific project. Mixing funds between projects can lead to financial mismanagement, legal issues, and can compromise the quality and completion of the projects.
