pericardium, atrium, and ventricle
middle layer, deep layer, and epicardium
endocardium, superficial layer, and deep layer

Explanation:

The heart wall has three distinct layers with specific names. The outermost layer is the epicardium, the middle layer is the myocardium (responsible for the heart's contraction), and the innermost layer is the endocardium. The other options either use non - specific terms (like'superficial layer','middle layer', 'deep layer') or include non - layer structures (pericardium is a sac around the heart, atrium and ventricle are heart chambers).

Answer:

Epicardium, myocardium, and endocardium
