In a relational table, what is the smallest unit of data?

Explanation:
In a relational table, data is stored cell by cell. Each cell is the intersection of a row and a column and holds a single data item—the value. Rows are collections of these values forming a record; columns define the type of data for each row; a table is the whole set of rows. The smallest unit you can store or retrieve directly is that single value in a cell (even if it’s NULL). So the correct answer is the value.
