Which of the following icons indicates that the particular field is set as the Primary key?
Answers
Explanation:
A table is a database object that you use to store data about a particular subject, such as employees or products. A table consists of records and fields.
Each record contains data about one instance of the table subject, such as a particular employee. A record is also commonly called a row or an instance.
Each field contains data about one aspect of the table subject, such as first name or e-mail address. A field is also commonly called a column or an attribute.
A record consists of field values, such as Contoso, Ltd. or [email protected]. A field value is also commonly called a fact.

A database can contain many tables, each storing information about a different subject. Each table can contain many fields of different types of data, such as text, numbers, dates, and hyperlinks.
External data
You can link to a variety of external data sources, such as other databases, text files, and Excel workbooks. When you link to external data, Access can use the link as if it were a table. Depending on the external data source and the way that you create the link, you can edit the data in the linked table, and can create relationships that involve the linked table. However, you cannot change the design of the external data by using the link.
Table and field properties
Tables and fields have properties that you can set to control their characteristics or behavior.

In an Access database, table properties are attributes of a table that affect the appearance or behavior of the table as a whole. Table properties are set in the table's property sheet, in Design view. For example, you can set a table's Default View property to specify how the table is displayed by default.
A field property applies to a particular field in a table and defines one of the field's characteristics or an aspect of the field's behavior. You can set some field properties in Datasheet view. You can also set any field property in Design view by using the Field Properties pane.

Explanation:
In computing, icons are pictograms or ideographs that appear on your computer screen to help you navigate your computer system. The symbol itself is an easy-to-understand symbol of a software tool, function, or data file accessible to the system, more like a traffic sign than a detailed representation of the actual entity. [1] It acts as an electronic hyperlink or file shortcut to access the program or data. Users can activate the icon using the mouse, pointer, finger, or more recently voice commands.
