If your body has been cleared of toxins through sweating from exercise, there is no reason to believe that you would feel a sense of (A) disarray or (B) turbulence, which are both terms for "disorder." Additionally, choice (D) quintessence doesn't make sense in this context, since it is a word for "a most typical example" or "concentrated essence." (F) exhilaration may seem like a plausible choice if you or a friend has ever described yoga as leaving you in a state of being "energetic" or "filled with happiness." But nothing from this particular sentence implies that a person would feel especially happy after finishing a hot yoga session. Rather, this sentence highlights the fact that sweating plays a role in cleansing a person's body. Therefore, the correct choices are (C) purgation, "the process of cleansing or purification," and (E) ablution, "the act of cleansing."
