The correct answer is option 2: Constitutional Right.

A constitutional right refers to a right that is guaranteed and protected by a country`s constitution. In this case, the right to vote in elections to a Parliament is a constitutional right because it is explicitly mentioned and protected in the country`s constitution. Constitutional rights are typically considered fundamental rights as they form the foundation of a democratic society and ensure the participation of citizens in the decision-making process. Legal rights, on the other hand, are derived from laws enacted by the Parliament and can be changed or modified through legislative processes. Natural rights are inherent to all individuals and are not dependent on any governing authority. Therefore, the right to vote in elections to a Parliament falls under the category of a constitutional right.
