Answer :

Final answer:

The heart is positioned superior to the diaphragm with its apex tilted to the left, located within the thoracic cavity between the lungs. So, the correct option is (A) Superior to the diaphragm, where its pointed apex tilts to the left.

Explanation:

The heart sits superior to the diaphragm, where its pointed apex tilts to the left. This is because the human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. The apex of the heart, which is the inferior tip, lies just to the left of the sternum, between the junction of the fourth and fifth ribs near their articulation with the costal cartilages. The right side of the heart is deflected anteriorly, and the left side is deflected posteriorly, helping to explain the heart's slight left orientation within the chest.
