An all-India service can be created

Correct option is A

The correct option is: (a) in accordance with the procedure prescribed under Article 312 of the Constitution of India

Explanation:

An All-India Service (AIS) can be created only through the constitutional mechanism provided under Article 312 of the Constitution of India.

• Article 312 empowers Parliament to create one or more All-India Services common to the Union and the States, such as the IAS, IPS, and IFS.
• However, this power can be exercised only after:
• The Council of States (Rajya Sabha) passes a resolution
• The resolution must be supported by not less than two-thirds of the members present and voting
• The resolution must declare that it is necessary or expedient in the national interest to create such a service
• After this resolution, Parliament may by law create an All-India Service.

Therefore, the creation of an All-India Service must strictly follow the procedure under Article 312.
