Choice "D" is correct. Bankruptcy Code section 727(d) sets out the reasons for revoking a discharge. The grounds include failing to answer a material question on the bankruptcy petition if the question has been approved by the court, unless the fifth amendment privilege against self-incrimination is appropriately claimed. Thus, II could be a ground for revocation. The grounds do not include failure to list one creditor. Thus, I is not a possible ground.
