Final answer:
Eastern Iranian languages are associated with the Caucasian or White race and belong to the Indo-European language family, with Persian as an example.
Step-by-step explanation:
The Eastern Iranian languages belong to the Indo-European language family and are associated with the Caucasian or White race, which includes people of European, Middle Eastern, and North African origin. The concept of categorizing languages by race is outdated and is based on historical classifications. Modern linguistics and anthropology focus on language families and cultural backgrounds rather than racial categories.
The Indo-European family comprises several language branches, including the Indo-Iranian languages, which consist of the Indo-Aryan and Iranian languages. The Persian language is an example of an Iranian language, with Iran contributing significantly to various fields such as arts, mathematics, and science throughout its history.
