The correct answer is (d).
The Constitution of India does not provide for the inclusion of a Union territory in a state. However, it does provide for the formation of new states by the Parliament, by increasing the area of any state, diminishing the area of any state, altering the name of any state, or by uniting two or more states or parts of states or by uniting a part of any state with any other state.
The Constitution also provides for the creation of new Union territories by the Parliament. The Parliament may, by law, create new Union territories, or alter the boundaries of any existing Union territory.
The Constitution does not provide for the inclusion of a Union territory in a state because it is considered that a Union territory is a separate entity from a state. A Union territory is not a part of any state, and it is governed directly by the Central Government.
