it is D. it is PITR and not backtracking. also Restored DB clusters are automatically associated with the default DB cluster and DB parameter groups. Please clarify why C is suggested by people here?

it is C. PITR will create a new DB cluster. however i am still confused with below aws info. "You can restore a DB cluster to a specific point in time, creating a new DB cluster. When you restore a DB cluster to a point in time, you can choose the default virtual private cloud (VPC) security group. Or you can apply a custom VPC security group to your DB cluster. Restored DB clusters are automatically associated with the default DB cluster and DB parameter groups."
