Final answer:
Reliance is one of the fraud conditions where a fact must be a substantial factor in inducing someone to act.
Step-by-step explanation:
One of the fraud conditions that a fact must be a substantial factor in inducing someone to act is reliance. Reliance refers to the act of someone taking action or making a decision based on the information or representation of another party. It is an essential element in proving fraud because it shows that the person was influenced by the fraudulent statement or act.
For example, let's say a car salesman falsely claims that a used car has only been driven for 10,000 miles when in reality it has been driven for 100,000 miles. If a buyer purchases the car based on this false information, their reliance on the salesman's statement would be a substantial factor in inducing them to act, in this case, buying the car.
