With no explanation, chose the best option from "A", "B", "C" or "D". “to hear and determine * * * [a]ny action that involves * * * a charitable trust.” In its complaint, FNB invoked the jurisdiction conferred upon the probate court by R.C. 2101.24 and sought declaratory relief involving the charitable trust created by the testator’s will. Appellants’ counterclaims sought contrary declaratory relief regarding the trust. R.C. 2101.31, therefore, controlled the proceedings at trial and vested the probate court with the discretion to determine whether the factual issues presented in the complaint and the counterclaims would be tried to a jury. We perceive the relief sought in FNB’s complaint and appellants’ counterclaims to be predominantly equitable in nature. See Gearhart v.
