Out of the given options, 'Largely English in the seventeenth century, non-English in the eighteenth century' is the best one that describes the pattern of immigration into Britain's North American colonies during the years 1620 to 1770.

Explanation:

From 1620 to 1700, the immigrants immigrating to British colonies in North America were mostly English, from 1700 to 1770, the number of non-English immigrants immigrating to there, exceeded English immigrants.

As the first colonies were set up by the British in the newly found continent of North America, most immigrants that came here to settle were from their own country.

As the people from a few other European countries started to come to know about the life and opportunities in the British colonies, the population of non-English immigrants exceeded.
