Explanation
In a Republican State, the Head of the State is elected.
A republican form of government is one in which the Head of the State is not a monarch, but rather a person who is elected by the people or their representatives. In a republican state, the Head of the State may hold either ceremonial or executive powers or both, depending on the specific form of government.
For example, in the United States, which is a federal republic, the Head of the State is the President, who is elected through an electoral college system. Similarly, in India, which is a parliamentary republic, the Head of the State is the President, who is elected by an electoral college comprising of members of both houses of the Parliament and the State Legislative Assemblies.
Thus, the correct answer to the question is D: Elected.
