As long as an instrument is suitable to prove a fact, it is admissible as evidence; provided that it possesses other requisites determined by the Statute. Types of evidence that are stated by the Statute include (1) documents (belge) and (2) deeds (senet), (3) oath (yemin), (4) witness (tanık), (5) expert examination (bilirkişi incelemesi) and (6) inspection by judge (keşif), and (7) Res judicata (kesin hüküm). Preliminary examination is not one of the types of evidence. It refers to the process through which the court examines procedural requirements and preliminary objections, determines boundaries of the dispute, carries out preparatory proceedings and proceedings necessary for the parties to present evidence and for the discovery of evidence, and encourages the parties for settlement or mediation. The correct answer is E.
