Correct Answer: Both the union and state governments

Solution : The correct option is both the union and state governments.

Members of All India Services work for both the union government and their respective state governments. The Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Forest Service (IFS) are among these services. While they are recruited by the Union Public Service Commission (UPSC) through the Civil Services Examination, their services can be assigned to both the central and state governments, depending on their postings and responsibilities.
