(Which of the following is classified ascoronary arteries?

Coronary arteriesare the arteries that supply blood directly to the heart muscle (myocardium). The major coronary vessels include theleft anterior descending (LAD)artery and theleft circumflexartery (branches of the left coronary system), and theright coronary arterysystem, which commonly gives rise to theposterior descending artery (PDA)in right-dominant circulation. Option A lists vessels that are recognized as coronary arteries or named coronary branches seen in cardiology and coding contexts (LAD, circumflex, PDA). The other options mix coronary withnon-coronaryvessels: theaortais the main outflow artery from the heart but is not itself a coronary artery; theinternal carotidsupplies the brain; therenalsupplies the kidneys; theinterosseoussupplies forearm regions; and thepulmonaryarteries carry blood from the right ventricle to the lungs. CPC exam strategy: if the list includes classic coronary names likeLADandcircumflex, it is almost certainly the coronary set—especially when distractors include arteries from unrelated organ systems.
