With no explanation, chose the best option from "A", "B", "C" or "D". interests ... are not limited by a few rigid, technical forms,” Perry v. Sindermann, 408 U.S. 593, 601, 92 S.Ct. 2694, 33 L.Ed.2d 570 (1972), the Due Process Clause’s “procedural component does not protect everything that might be described as a benefit.” Town of Castle Rock, Colo. v. Gonzales, 545 U.S. 748, 749, 125 S.Ct. 2796, 162 L.Ed.2d 658 (2005) (quoting Roth, 408 U.S. at 577, 92 S.Ct. 2701). State law, contract, or a promise implied from circumstances, are generally sufficient to create a property interest protected by due process. See e.g., Loudermill, 470 U.S. at 538-39, 105 S.Ct. 1487 (finding that a state statute, permitting employee dismissal only for cause, created a property interest in continued employment); see also Leary v. Daeschner, 228 F.3d 729, 742 (6th Cir.2000) (<HOLDING>); Ramsey v. Bd. of Educ., 844 F.2d 1268, 1272
