Answer:

The correct option is : a. serous fluid in the pericardial cavity

Explanation:

The heart is enclosed in a sac containing the heart, known as the  pericardium. The pericardium has two layers- fibrous and serous layer.

The serous layer of the pericardium produces and secretes the pericardial fluid into the pericardial cavity.

The pericardial fluid is a lubricating serous fluid present in the pericardial cavity. It reduces the friction caused between the pericardial membranes by lubricating the epicardial surface.
