The answer will be assess future human resource demand. Why? Well, let's consider all the options given. For Human Resource (HR) planning we cannot straight away jump to creating a job analysis without deciding on one job & how much it's worth or important in the future. The second option is to create or establish a strategic plan. That too won't work without knowing which occupation is needed more in the future. 4th -> create an inventory of the organization's employees. Well, that's a no-no, we need to find a future-needy job before selecting the people. So, the 3rd option is the most appropriate answer.
