The correct answer is option 'C': Right to freedom.

Explanation:
The right to freedom is restricted for Hannah in her country. In a democratic system, citizens are typically granted certain fundamental rights and freedoms to ensure that they have a voice in the governance of their country. However, in Hannah's country, there is a restriction on sharing any observations about the leader of the country. This limitation infringes upon the right to freedom, which includes the freedom of speech, expression, and opinion.

Below is a detailed explanation of the provided answer:

1. Right to freedom:
The right to freedom is a fundamental democratic right that encompasses various aspects such as freedom of speech, expression, assembly, association, and movement. It allows individuals to express their opinions, thoughts, and observations freely without fear of persecution or reprisal. However, in Hannah's country, citizens are not permitted to share any observations about the leader of the country. This restriction directly infringes upon the right to freedom as it curtails the freedom of speech and expression.

2. Election of representatives:
One of the democratic rights that Hannah is allowed to exercise is the right to elect representatives. This means that she can participate in the electoral process and vote for candidates who will represent her interests in the government. This right ensures that citizens have a say in the decision-making process and can hold their elected representatives accountable for their actions.

3. Right to equality:
The right to equality ensures that all individuals are treated equally before the law and have equal access to opportunities and resources. It prohibits discrimination based on factors such as gender, religion, race, or social status. While the question does not provide any information about the restriction of the right to equality for Hannah, it is important to note that this right should be upheld in a democratic system.

4. Right to be treated fairly:
Similar to the right to equality, the right to be treated fairly ensures that individuals are not subjected to unfair treatment or discrimination. It ensures that everyone is given equal opportunities and protection under the law. Again, the question does not specify any limitations on this right for Hannah.

5. Right to information:
The right to information guarantees citizens the access to information held by public authorities, allowing them to make informed decisions and hold the government accountable. While this right is not explicitly mentioned in the question, it is not restricted for Hannah as she is attaining the voting age and is happy that she can vote.
