Answer 2

Required is the property that is equivalent to NOT NULL.

Option: (c)

Explanation:

The property which is equivalent to NOT NULL can be referred as ‘Required’. In the Forms, when the user specifies the property as "Required" then that particular field should not be left blank.  

This is similar to the case of NOT NULL in the query. For example, Create table tablename ("col_name" VAR_CHAR (25) NOT NULL); specifies that the column col_name requires a value in the field and it cannot be left blank, this is similar to the ‘Required’ property in the forms.
