Which of the following describes 'Alien Friend'?

The term 'Alien Friend' refers to a foreign national who is not only residing in a country but is also in a peaceful relationship with that country. This classification typically implies that the foreigner does not pose a threat to the host nation's safety or security and is, therefore, allowed certain legal rights and privileges within that country.

In many legal contexts, such as immigration law and treaty provisions, the status of 'Alien Friend' can afford individuals access to various rights that may not be granted to those designated differently, such as 'Alien Enemies.' This inclusion typically allows them to engage in business, own property, and participate in societal functions, as long as they are not contravening any laws.

The reasoning behind the other options lies primarily in their definitions, which do not capture the essence of being an 'Alien Friend.' A foreigner without legal rights can typically not be categorized as an 'Alien Friend', nor does a foreigner with a criminal record maintain a peaceful status with the host country. Thus, the key aspect of 'Alien Friend' hinges on the peaceful relationship and mutual respect between the foreigner and the host nation, aligning perfectly with the notion presented in the correct answer.
