Relations in the context of databases are indeed two-dimensional tables where each column has a distinct name and the order of columns does not matter. However, the entries (or values) in each column of a relation are single-valued, adhering to the principle of atomicity in the relational database model. This means option B, which suggests entries can be double-valued, is false.
