What is included in the concept of accession?

Accession refers to a legal concept in property law that involves the acquisition of ownership rights through the natural increase or addition to property. This can include both manmade improvements, such as buildings or fixtures that one adds to a property, and natural additions, such as soil deposits from a river or the growth of crops. The essence of accession is that it signifies how property can expand or increase in value through enhancements or natural phenomena.

In this context, the other options focus on aspects of property management or financial transactions rather than the physical expansion or improvement of property itself. Accessing the concept of accession effectively involves understanding the implications of changes to the property, not merely financial transactions or rights associated with the property. Thus, option C accurately encompasses the full scope of what accession entails.
