In the context of data representation and information systems, how do "geometry" and "semantics" differ?
A) Geometry refers to the physical layout of data, while semantics refers to the meaning of data elements
B) Geometry involves the data format, while semantics deals with the algorithms used for processing data
C) Geometry is concerned with data encryption, whereas semantics focuses on data compression techniques
D) Geometry and semantics are interchangeable terms that both refer to the structure of data
