The correct Answer is:
A
Heart is enclosed in a tough, two layered fibrous sac, the pericardium. The outer layer is non distensible fibrous pericardium and inner layer is thin serous pericardium which further consists of outer parietal layer and inner visceral layer. Between the parietal and visceral layers occurs as a narrow pericardial space, the pericardial cavity which is derived from coelom and is filled with serous pericardial fluid for frictionless movement and protection from shock and mechanical injury.
