Answer:
Boolean
Explanation:
Boolean is one of the primitive data types that will only hold either true or false value. This data type is commonly used in a variable that will track a status with only two possible outcomes.
For example, the<em> ParticipantPD</em> field is to track the payment status (paid or unpaid) of a participant. So, declare the<em> ParticipantPD</em> field as boolean data type will meet its purpose.
boolean ParticipantPD = true;
or
boolean ParticipantPD = false;
It is a number that is expressed in the binary numerical system
