Answer
(B) the human brain often orchestrates physiological responses without any conscious effort on the part of an individual.
Explanation
The question is about structuring the sentence in a clear and grammatically correct manner. It tests understanding of syntax, sentence structure, and clarity. We need to ensure the sentence logically communicates that the human brain orchestrates physiological responses without an individual's conscious effort. Option A (NO CHANGE) is awkward and unclear in its phrasing.Option B ("the human brain often orchestrates physiological responses without any conscious effort on the part of an individual") removes redundancy, simplifies the sentence, and clearly states the concept.Option C ("physiological responses are often orchestrated by the human brain without any conscious effort on the part of an individual") is also correct but is slightly less direct.Option D ("individuals are often unaware of the physiological responses the human brain orchestrates") changes the emphasis in an unnecessary way, shifting focus to the individuals' awareness rather than the brain's function.
