The correct answer is: The Union Public Service Commission with the approval of the Lieutenant Governor shall serve the needs of the Union Territory of Ladakh.
The Union Public Service Commission (UPSC) is an independent body constituted by the Constitution of India to conduct the Civil Services Examination, the Indian Administrative Service Examination, the Indian Foreign Service Examination, and other allied examinations. The UPSC is also responsible for advising the Government of India on matters relating to public service.
The Lieutenant Governor of Ladakh is the head of the Union Territory of Ladakh. The Lieutenant Governor is appointed by the President of India on the advice of the Central Government. The Lieutenant Governor is responsible for the administration of the Union Territory of Ladakh.
The UPSC with the approval of the Lieutenant Governor shall serve the needs of the Union Territory of Ladakh. This means that the UPSC will conduct the Civil Services Examination and other allied examinations for the Union Territory of Ladakh. The UPSC will also advise the Lieutenant Governor on matters relating to public service in the Union Territory of Ladakh.
The other options are incorrect because they are not the head of the Union Territory of Ladakh. The Prime Minister is the head of the Government of India, the President is the head of state of India, and None of the above is not a valid option.
