Which of the following sentences is relevant to the passage prior to the concluding sentence?

The correct answer is D because this sentence aligns with the positive effects of yoga discussed in the passage, emphasizing how it helps in relieving tension and stress. It complements the theme of the passage, which focuses on the benefits of yoga for mental and physical well-being. Choices A, B, and C either introduce unrelated information or present a negative aspect that does not correspond with the passage's positive tone. Therefore, option D is the most relevant sentence to the passage prior to the concluding sentence.
