Answer to Question 1

B
Explanation: If you do not recall the individual conditions, utilize deconstructing terms to reason it out. Patent means open, a duct is a tube in layman's terms, and arteri/o is the combining form for artery. These word parts are similar to the key ones in the question, opening between pulmonary artery and aorta, which is also an artery.

a. hypo-: means under
b. epi-: means above
