The term field as applied to the database table means:

Vertical column of the table

The correct answer is option 4- Vertical column of the table.

In DBMS, data is organised in tables (similar to a file). A table has a number of rows (or records) and columns (or fields or attributes). Each row contains a record of information, for example of an account head or a party or a transaction as per the need. The information in a row consists of a sequence of columns or attributes, such as transaction number, transaction date, etc, or it could be party’s name, party’s address, etc.
