Step-by-step explanation:
The correct response to the question about the nature of German migration to the English colonies is option c. was to frontier areas as farmers. Throughout the colonial period, many European immigrants, including Germans, moved to the colonies for various reasons, such as seeking economic opportunity or religious freedom. German migrants, in particular, often settled as farmers in frontier areas, contributing to the diverse population and agricultural development in the English colonies.
They were a part of the broader picture of European migration, alongside English indentured servants working in tobacco fields and slaves that were forced into labor in various colonies. The Germans largely settled in the interior regions rather than participating predominantly in roles such as slaveholders or fur trappers, though the colonial communities were indeed complex and varied.
