Which combining form means 'heart'?

Explanation:
The concept tested here is recognizing the combining form that names a body part. The combining form for heart is cardi/o (also seen as cardio- when joined to vowels). It is used to build terms like cardiology, cardiovascular, and cardiac, all relating to the heart. The other options map to different organs: gast/o refers to the stomach, nephr/o to the kidney, and pulmon/o to the lung. So the best answer is the one that uses cardi/o to denote the heart.
