Answer: (B)

The key idea here is how evidence of other acts is treated under Rule 404(b) in civil versus criminal cases. In civil cases, such acts can be admitted to prove an essential element of a claim or defense—for example, showing knowledge, intent, or absence of mistake when those are required elements of the civil issue. In criminal cases, the bar is much higher because the risk is unfair prejudice against the defendant, so other-acts evidence is normally excluded unless the act itself is an essential element of the charged offense. In that narrow situation, the prior act is admissible because it directly proves a required element of the crime, not because it speaks to propensity. That’s why the strongest fit is: civil cases permit admission to prove an essential element, while criminal cases allow it only if the prior act is itself an essential element of the offense.
