Explanation:

 According to Article 239, The Union Territories are administered by the President through an administrator, who is appointed by him with a suitable designation. This designation is called either Lieutenant Governor or Chief Commissioner or Administrator. The two UTs with Legislatures and the UT of Andaman and Nicobar Islands have Lt. Governors as Administrators. The Governor of Punjab functions as the Administrator of the UT of Chandigarh and a senior IAS officer functions as Advisor to the Administrator. The remaining 3 UTs viz. Daman and Diu, Dadra and Nagar Haveli and Lakshadweep are administered through IAS officers who are appointed as Administrators.

The President appoints Advisory Committee for each Union Territory, where there is no representative government. The President appoints eminent citizens of Union Territory as members of Advisory Committee. The President consults the Advisory Committee in matters of governance. In Delhi and Puducherry, the President, not Lt. Governor, appoints Chief Ministers and other Ministers
