Answer:
Patent ductus arteriosus (PDA) is an extra blood vessel found in babies before birth and just after birth.
Explanation:
The ductus arteriosus is a normal blood vessel that connects two major arteries — the aorta and the pulmonary artery — that carry blood away from the heart.
The lungs are not used while a fetus is in the womb because the baby gets oxygen directly from the mother's placenta. The ductus arteriosus carries blood away from the lungs and sends it directly to the body. When a newborn breathes and begins to use the lungs, the ductus is no longer needed and usually closes by itself during the first 2 days after birth.
If the ductus doesn't close, the result is a patent (meaning "open") ductus arteriosus. The PDA lets oxygen-rich blood (blood high in oxygen) from the aorta mix with oxygen-poor blood (blood low in oxygen) in the pulmonary artery. As a result, too much blood flows into the lungs, which puts a strain on the heart and increases blood pressure in the pulmonary arteries.

The answer should be C, they focus on using resources that can be renewed.
In order to become sustainable, industries have to maintain a balance between economic, social and environment. If they focus on only one or two aspects, they may not be able to become sustainable.
Economic aspects may include diversifying the ecomic structure; social aspects may include setting a minimum wage level for workers, providing a good working environment; and environment may include using renewable resources in production or handling their own pollutants.
Therefore, if they only focus on economic aspects such as maximizing productivity or profit, they may cause a lot of damage on the environment or even cause problems to the workers. So, the best answer is C. It also focuses on the environment, so that resources may be less likely to run out.
