The speaker in the given excerpt is a first-person speaker.

The given excerpt uses pronouns like "I" and "me" which are characteristic of the first-person point of view. This indicates that the speaker is referring to themselves, narrating their own thoughts, actions, and beliefs.

Option B: Second person would use "you," addressing the reader or another person directly, which is not present here.

Option C: Third person would use "he," "she," "they," or names to describe someone else, which is also not present.

Option D: The consistent use of "I" makes the first-person perspective of the speaker clear. Therefore, this option is not correct.
