Final answer:
The statement is true as laws create a predictable framework essential for business planning.
Step-by-step explanation:
The statement "One of the most important functions of law in the business environment is to facilitate planning" is true. Laws provide a framework that businesses can rely on for planning their operations, investments, and growth strategies. They ensure that there is a degree of predictability in the business environment which is critical for long-term planning and investment. Laws cover a wide range of areas including commerce, labor, intellectual property, and environmental regulation. This creates a stable and orderly marketplace where businesses know what is expected of them and what they can expect from others. Therefore, the function of law goes beyond just restricting or controlling behaviors; it also facilitates business by helping to create an environment where strategic planning is possible.
