(b) No other record of the proceedings upon the trial thereof can be obtained.

(c) Such action or proceeding is subject to review by motion for new trial pending at the time of such loss or destruction.

(d) The court in which such action or proceeding is pending deems it impossible or impracticable to restore such proceedings and to settle a bill of exceptions or statement of the case containing such proceedings, so as to enable the court to review the judgment or order therein by motion for new trial.
