The answer is A. Record.
A record is a collection of fields that contains data about one entity. For example, a customer record might contain fields for the customer’s name, address, phone number, and email address.
A file is a collection of records. For example, a customer file might contain records for all of the customers of a company.
A field is a single piece of data in a record. For example, the customer’s name is a field in a customer record.
A document is a collection of fields and records that is used to store information. For example, a sales order document might contain fields for the customer’s name, address, phone number, and email address, as well as fields for the products that the customer ordered and the prices of those products.
None of the above is not the correct answer because it does not specify which of the options is correct.
