Final answer:
The primary goal of Giovanni Aldini's experiments with electricity on Forster's body was scientific discovery, seeking to expand upon Luigi Galvani's findings on electrophysiology and the effects of electricity on biological tissues.
Step-by-step explanation:
The primary goal of Giovanni Aldini's experiments with electricity on Forster's body was c) Scientific discovery. Aldini was inspired by the discoveries in electricity made by scientists such as Luigi Galvani, who conducted experiments on the effects of static electricity on muscles of dead frogs. Galvani's research, which suggested that animal tissues contained their own form of electricity, paved the way for Aldini's work. Aldini utilized Galvani's findings and the understanding of electricity's interaction with biological tissues to further investigate the principles of electrophysiology. While his public demonstrations often appeared as entertainment, his underlying objective was to explore the effects of electricity on the human body and to potentially uncover new scientific and medical understandings.
