With no explanation, chose the best option from "A", "B", "C" or "D". under the Bankruptcy Act of 1898, section 2a(15) (former 11 U.S.C. § 11a(15)), which provided that only the District Court, not the bankruptcy court, could enjoin a court. Section 105(a), through the elimination of the restriction contained in the prior law, strongly suggests that Congress intended that a bankruptcy court could enjoin another tribunal when appropriate. Indeed, if the Commission has not previously been enjoined by a bankruptcy court, numerous other administrative agencies have been. See, e.g., NLRB v. Superior Forwarding, Inc., 762 F.2d 695, 699 (8th Cir.1985) (affirming bankruptcy court’s injunction against NLRB); In re Hunt, 93 B.R. 484, 491-98 (Bankr.N.D.Tex.1988) (enjoining Commodities Futures Trading Commission); In re Bulldog Trucking, In ankr.N.D.Cal.1987) (<HOLDING>). The court thus concludes that it may enjoin

A: holding that bankruptcy court may enjoin state environmental reclamation order
B: holding that bankruptcy court may enjoin federal administrative proceedings when they threaten the debtors estate
C: holding that creditor lacked appellate standing to appeal order of bankruptcy court absent permission of bankruptcy court
D: holding that bankruptcy court could not enjoin third party tort claims that would not affect estate
