With no explanation, chose the best option from "A", "B", "C" or "D". rulings are generally to the effect that § 106(a) fails the second prong of the abrogation test; although Congress obviously intended to abrogate state sovereign immunity when it enacted § 106(a), these circuits have held that it did not act pursuant to a “valid exercise of power” in carrying out that intent. Section 106(a) is an exercise of Congress’s powers under the Bankruptcy-Clause of Article I of the Constitution. See Mitchell, 209 F.3d at 1119; Sacred Heart Hosp., 133 F.3d at 244-45; Fernandez I, 123 F.3d at 245; Schlossberg, 119 F.3d at 1146-47. Although the Supreme Court has yet to address squarely whether the Bankruptcy Clause provides a legitimate basis for abrogation, cf. Tenn. Student Assistance Corp., — U.S. —, 124 S.Ct. 45, 156 L.Ed.2d 703, the Court’s precedents hav 114 (<HOLDING>). In other words, there is some doubt about

A: holding the sixth amendment applicable to the states through the fourteenth amendment
B: holding that bankruptcy jurisdiction is not within section 5 of the fourteenth amendment
C: holding that fourteenth amendment is the only recognized source of authority for abrogation
D: holding that fourteenth amendment only applies to state action
C.
