The root 'cardi/o' refers to which body part?

Explanation:
Cardi/o points to the heart. In medical language, roots indicate the organ or system involved, and cardio- or cardi/o appears in terms like cardiac (relating to the heart), cardiology (the study of the heart), and cardiovascular (relating to the heart and blood vessels). That linkage to the heart is why this root is tied to that body part. Other options use different roots: the lung is linked to pulmon/o or pneumon/o, the brain to cerebr/o or encephal/o, and the stomach to gastr/o. So the heart is the body part associated with cardi/o.
