Final answer:
In a civil case, the burden of proof standard is 'preponderance of evidence,' which means the evidence must favor the plaintiff's case more likely than not. The correct answer is option D.
Step-by-step explanation:
The burden of proof standard that must be met in a civil case is D. preponderance of evidence. This means that the plaintiff must prove that it is more likely than not that their claims are true. It is a lower standard compared to the criminal standard of beyond a reasonable doubt, which requires a much higher level of certainty to convict a defendant. In a civil case, the evidence must simply weigh more heavily in favor of the plaintiff for them to succeed.
