Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is c)field.
As we know that the feature of an entity is represented by its attribute in the database table. A database table is a set of records of different fields. Each field represents a row in a database table. Each field can contain a set of attributes related to an entity such as a paint color.
So the price of paint will be in its own field. Because there are different colors in the database table. Each color has its own record in form of a field. As you know that each field is a row in the database table. So, each row has the price of a paint color.
Other options are not correct because:
The table contains a list of fields and each field contains its own paint price. The format and file is something different and does not have any relation with the question scenario.
