With no explanation, chose the best option from "A", "B", "C" or "D". is expressly so despite the statutory authority of any federal agency “to sue and be sued.” See Bor-Son Bldg. Corp. v. Heller, 572 F.2d 174, 177 (8th Cir. 1978) (12 U.S.C. § 1702); Freeling v. FDIC, 221 F.Supp. 955, 956-57 (W.D.Okla.1962), aff’d on basis of district court’s opinion, 326 F.2d 971 (10th Cir. 1963). In Bor-Son Building Corp. v. Heller, 572 F.2d 174 (8th Cir. 1978), this court reasoned that the FTCA is the exclusive remedy if: (1) the suit is against a federal agency; and (2) the suit sounds in tort. 572 F.2d at 177. The instant case meets both requirements. First, it is not disputed that the SBA is a “federal agency” within the meaning of section 2671 of the FTCA. 15 U.S.C. § 633; see also SBA v. McClellan, 364 U.S. 446, 448-50, 81 S.Ct. 191, 194, 5 L.Ed.2d 200 (1960) (<HOLDING>). Second, it should be readily apparent that

A: holding that a formal report is not required when determining causation is an integral part of treating a patient
B: holding sba is an integral part of federal government and is not a separate legal entity
C: holding that a tree is part of a public facility if a public entity incorporates it into a facility in such a manner that it 1 becomes an integral part of the facility and 2 is essential for the intended use of the facility
D: holding that a sole proprietorship was not a separate legal entity capable of being sued under ohio law
B.
