Option 1 is correct. The All India Services can only be created by an Act of Parliament. This means that a specific law needs to be passed by the Parliament in order to establish the All India Services. These services include the Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Forest Service (IFS). The creation of these services is not within the purview of the executive or the UPSC (Union Public Service Commission). The UPSC is responsible for conducting the recruitment process for these services, but it does not have the authority to create or establish them. It is the Parliament that has the power to enact legislation to create these services. Therefore, option 1 is the correct statement about the All India Services.
