{'renal vein': [3, 0, 1, 1], 'kidneys': [3, 0, 0, 0], 'pulmonary vein': [2, 0, 1, 1], 'coronary artery': [0, 0, 0, 1], 'blood': [5, 0, 0, 1], 'heart muscles': [0, 0, 0, 1], 'lungs': [3, 0, 0, 1]}

Option 1 states that coronary artery supplies blood to heart muscles. This statement is correct. The coronary arteries are responsible for supplying oxygenated blood to the muscles of the heart.

Option 2 states that pulmonary vein supplies blood to the lungs. This statement is also correct. The pulmonary veins carry oxygenated blood from the lungs back to the heart.

Option 3 states that hepatic artery supplies blood to the kidneys. This statement is incorrect. The hepatic artery actually supplies blood to the liver, not the kidneys.

Option 4 states that renal vein supplies blood to the kidneys. This statement is correct. The renal vein carries deoxygenated blood from the kidneys back to the heart.

Therefore, the correct answer is option 2, as both statements 1 and 2 are correct.
