With no explanation, chose the best option from "A", "B", "C" or "D". to comply with both. Florida Lime & Avocado Growers, Inc. v. Paul, 373 U.S. 132, 143, 83 S.Ct. 1210, 10 L.Ed.2d 248 (1963). Here, it is not possible for the debtor to transfer his legal right to the inheritance to the trustee to be administered as property of the estate as required under 11 U.S.C. §§ 541 & 542 and also exercise his disclaimer right under Va.Code Ann. § 64.1-196.4. As with the federal grant of exemptions in the Code allowing debtors to exclude certain property from the estate, even state exemption statutes in "opt-out" states arise by the federal grant of exemptions in § 522, the right to disclaim inheritance property and exclude it from the estate must come from an act of Congress. Cf. United States v. Irvine, 511 U.S. 224, 240, 114 S.Ct. 1473, 128 L.Ed.2d 168 (1994)

A: holding that federal courts presiding over causes of action created by state law should apply state substantive law but federal procedural law
B: holding that where a conflict between state and federal law is alleged it must be reasonable to conclude that congress would have intended to preclude the state law in question since it would make little sense to preempt state law in order to serve the purposes underlying federal legislation if congress itself would not require or admit of preemption of state authority
C: holding that the plaintiffs state law claims are preempted by federal law
D: holding federal tax law is not struck blind by state law right to inheritance disclaimer where congress has shown no intent to support state law legal fictions as touchstones of taxability
D.
