I apologize for the confusion in my previous response. The correct answer is A. The statement "The habitat must use fewer than 200,000 kg of materials" describes a constraint for the project. It specifies a limit on the amount of materials that can be used in the construction of the habitat.

A. The habitat must use fewer than 200,000 kg of Materials
