Answer:
The best answer to the question: Which excerpt from the passage best shows that the passage uses a sequential pattern, would be, C: First, colonists created settlements along the East Coast.
Explanation:
When talking about a sequential pattern, and not a descriptive pattern, we are looking for one trait and that is, when a text starts listing things, literally numerically organizing the events that took place, so that the reader can understand what happened first, what followed, and how, and in which order, things ended. In this excerpt, when the text uses the word "first", immediately the reader understands that a numerical list is being given and a sequential pattern is taking place.
