The feature that can be used to meet these requirements is two-step approval process. An approval process defines the steps and criteria for approving records. A two-step approval process requires two levels of approval before a record can be deleted. The app builder can configure an approval process for opportunities that requires sales reps to submit their delete requests for approval from their managers. Option A is incorrect because Process Builder with Submit for Approval action is not a valid feature, as Process Builder cannot submit records for approval. Option B is incorrect because Approval Process with a triggered Flow process is not a valid feature, as Approval Process cannot trigger Flow processes. Option C is incorrect because Approval Process with Time-Dependent Workflow action is not a valid feature, as Approval Process cannot use Time-Dependent Workflow actions.
