Explanation:

- Option 1: Establishing fair and equitable pay structure

- Correct Answer

- Job evaluation focuses on creating a consistent basis for determining the value of jobs, ensuring fair compensation based on the requirement, responsibilities, and relative difficulty of each job.

- Option 2: Analyzing requirements for updating technology

- This involves assessing technological needs within an organization, not directly related to job evaluation or pay structures.

- Option 3: Assessing safety requirements of jobs

- This refers to evaluating job roles for safety needs and implementing appropriate safety measures, not focused on pay equity.

- Option 4: Improving productivity

- While job evaluation can indirectly impact productivity by ensuring employee satisfaction, its primary aim is not to improve productivity directly.
