a) all data related to a particular subject kept in a group
b) a single row of information in a table
c) a single piece of data in a single row of a table

The answer is B, a single row of information in a table. Regarding answer C, single pieces of data (cells or fields) that describe related data entities can be combined into a single row, or database record. For example, the values in the single data fields FIRST NAME, MIDDLE NAME, and LAST NAME in a single row could define a record called EMPLOYEE NAME.
Multiple records make up answer A, which defines a table, or group of records, which defines EMPLOYEES.
All of the tables, records, and data are managed by answer D, an electronic filing system.
