Final answer:
Demonstrative evidence includes items like photos that are meant to help the court understand testimony or facts about the case. Examples include crime scene photos or diagrams that illustrate specific details like the trajectory of a bullet.
Step-by-step explanation:
An example of demonstrative evidence is b. photos. Demonstrative evidence refers to evidence in the form of objects, pictures, models, diagrams, or other devices that are meant to clarify the facts for the judge and jury. Such evidence is used to help a witness explain their testimony or to help the members of the court understand the context and details surrounding the case better.
For instance, photos from a crime scene can be used to give the court visual context about where certain events took place or where evidence was found. Similarly, diagrams might be used to illustrate the trajectory of a bullet, or models could be used to reconstruct an accident. While the actual knife or the fingerprint might be considered real evidence, and a handwritten note could be documentary evidence, photographs serve as a visual representation of this evidence.
