Final answer:
An instance where 'Coca Cola explodes in a person's hand' serves as an example of Res Ipsa Loquitur in product liability. This doctrine implies negligence may be inferred simply from the occurrence of the incident, given that the product was under the manufacturer's control and such accidents typically do not happen without negligence.
Step-by-step explanation:
An example of Res Ipsa Loquitur in product liability would be option b, 'Coca Cola explodes in a person's hand'. This legal doctrine is applied in cases where the accident is of a kind that ordinarily does not occur in the absence of someone's negligence and the instrumentality causing harm was under the control of the defendant. In this case, without direct proof of the manufacturer's negligence, the fact that a sealed soda bottle exploded on its own suggests that there might have been negligence in the bottling process, which is under the manufacturer's control.
On the other hand, a doctor leaving a sponge inside a patient is an example of medical negligence where the concept of Res Ipsa Loquitur may also be applied, as it is something that should not happen if the required professional care was taken. However, this is not a product liability situation. Product liability pertains specifically to manufacturers and distributors of tangible products who are responsible for harm caused by those products.
