Final answer:
The burden of proof in civil cases is 'Preponderance of the evidence' and in criminal cases, it is 'Proof beyond a reasonable doubt', making Option 2 the correct choice.
Step-by-step explanation:
The burden of proof standard used in civil cases is preponderance of the evidence; this means that the evidence presented by the plaintiff must weigh more heavily on their side to succeed in court.
Conversely, the burden of proof standard used in criminal cases is beyond a reasonable doubt; the state must present evidence that leaves no reasonable doubt in the minds of the jury that the defendant committed the crime.
Therefore, the correct answer is Option 2: Preponderance of the evidence; Proof beyond a reasonable doubt. In criminal law, where someone's liberty is at stake, the evidence must be convincing to such an extent that there would be no reasonable doubt left as to the defendant's guilt.
However, in civil law, where the dispute typically involves property or money, the evidence must simply show that it is more likely than not that the defendant is liable for damages.
