Nintex Multiple approver Task allocation

Hello experts,

I have one SharePoint multi people picker column called reviewer. I want to assign task to all reviewers.

I need approval from all reviewer, means task must be approved when its approved by all reviewer,

and if any single reviewer rejects task, then whole task need to rejected.

I am bit confused to implement this, as Flexi task having multiple option.

Which option i should take to accomplished this scenario.

Please help!
