1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

A It is incorrect as a commercial building with a capacity of 150 people will require more than 1 washroom for sanitary and health reasons. C: While technically more than one washroom is required, a minimum of three washrooms may not be sufficient for a commercial building with a capacity of 150 people. Additionally, having more than two washrooms may offer more convenience and easier access for individuals. D: Four washrooms may seem excessive for a building with a capacity of 150 people, and it may also be a waste of resources to build and maintain four washrooms when two would suffice. It is important to have enough washrooms, but not too many. Ultimately, the correct answer is B because having only one washroom would not be enough for a commercial building with a capacity of 150 people, and having three or more washrooms could be seen as excessive and inefficient. Two washrooms strike a balance between meeting the sanitary needs of the building's occupants while also being practical and cost-effective.
