Hello @sanasayyad!

The correct answer is the option #2: Incident table is extended from Task table.

Here is a brief explanation:

• In ServiceNow the Task table is a base table used to standardize task-like records.

• The Incident table is a child table that extends the Task table.

• This means:

  • Incident inherits all fields and behavior from the Task table (e.g., assigned_to, priority, state).

  • It's part of the table hierarchy: Task > Incident.

  • Extension allows reusability and consistency across all task-based processes like Incident, Change, Problem, etc.

The other options are incorrect because:

• "Incident table has a one to many relationship with the Task table" –> Not true; Incident is a type of Task, not related via a 1:N relationship.

• "Incident table is related to the Task table via the INC number" –> INC number (number field) is just a unique identifier, not a relationship key.

• "Incident table has a many to many relationship with the Task table" –> Incorrect; there is no M:N relation between Incident and Task. They are in a parent-child structure.

• "Incident table is a database view of the Task table" –> No, Incident is a physical table extended from Task, not a view.
