Answer :
Answer: B. Tachypnea
Explanation: Let's go over each of the vocabulary words and their medical prefixes and suffixes in order to better understand each of them.
Answer choice A is not a real word. Bracypriea is not a medical term nor a word used in any other discipline or field.
Answer choice C refers to a condition where an individual breathes in a larger volume of air than normal, but is still breathing at a normal rate.
Answer choice D refers to a condition where an individual as not breathing at all.
The meaning of many of these words can actually be derived fairly easily by their prefixes and suffixes. All of the vocabulary words have the suffix -pnea, which means that the term has relation to breathing. The prefix "tachy" in tachypnea means rapid and quick, thus the meaning of the entire word being "rapid breathing."
The prefix "hyper" in the medical fields refers to something that is abnormally high or excessive. In the case of hyperpnea, it refers to the excessively high volume of air inhaled.
Finally, the prefix "a" in apnea refers to a lack of something. In the word "apnea," it refers to a lack of breathing.
