Who is entitled to diplomatic immunity according to the text?

Diplomatic immunity is a legal provision that offers certain protections to specific individuals working on behalf of their governments in a foreign country. This principle is primarily designed to ensure that diplomatic personnel can perform their duties with freedom and security. The correct answer highlights that it is the employees of diplomatic missions and their families who are entitled to this immunity.

These employees typically include diplomats, ambassadors, and other official representatives who are engaged in diplomatic relations. Their immunity is essential for maintaining effective international relations, as it helps prevent harassment or coercion by the host country, thus allowing them to operate without fear of legal actions or detentions.

The other options do not accurately capture the scope of diplomatic immunity. For instance, not all foreign nationals or tourists are covered; only those specifically working for, or connected to, recognized diplomatic missions receive these protections. Similarly, not all elected officials from foreign governments are granted immunity unless they are part of a diplomatic mission. This targeted approach ensures that diplomatic immunity serves its intended purpose while balancing the host country's legal framework.
