You get a project to construct a school building. The client gives you their requirements, such as the size of the building, number of rooms, details of the playground, number of toilets, and paint color. You start working on the project. You estimate the budget, develop the plan, and create a schedule. After developing and approving the plan, you gather the team and move on to the execution phase. You bring workers to the site and start construction. You complete the school building and then verify with the client whether it is as per their requirements. Once the client is satisfied, you hand the school building over to them, get the final payment, and the project is closed. 

Based on the above scenario:

a) Determine which statement refers to project scope and product scope. 

b) Differentiate between project scope and product scope.
