Answer:
C) conversational
Explanation:
The best way to describe Thoreau's writing style is as conversational. Thoreau's writings can be considered a series of reflections. The author usually talks about the ideas that go through his mind, as well as the values that guide his actions. This reflective type of writing leads to a conversational style, where the writer talks to us as if we were having a conversation with him. Moreover, his tone is casual and informal.
