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.

<h3>What are RDAs? </h3>
The Recommended Dietary Allowances (RDAs) for critical nutrients have been assessed by the Food and Nutrition Board to be sufficient to cover the known nutrient needs of practically all healthy individuals.

History of RDAs. </h3>
The first Recommended Dietary Allowances (RDAs) were published in 1943, during World War II, with the stated purpose of “establishing criteria to serve as a target for appropriate nutrition.” According to “newer results,” it indicated the “recommended daily intakes for the major nutritional needs for people of different ages” (NRC, 1943).
The history of how the RDAs were developed is explained in-depth by the first chair of the Committee on Recommended Dietary Allowances (Roberts, 1958). Updates have been made to the original article.
