Which sentence properly uses subjunctive mood for hypothetical situations in legal contexts?

A. If the prosecutor evaluates a case thoroughly, they would find more evidence

B. Were the prosecutor to evaluate a case properly, they might reach different conclusions

C. The prosecutor evaluates cases as if he is always right

D. Should the prosecutor evaluated the case, the outcome will change

核心考点：虚拟语气在假设性法律情境中的应用。正确答案B使用'Were...to'结构符合规范的法律虚拟语气格式。A选项混合真实条件句与虚拟语气，C选项未使用虚拟结构，D选项动词形式错误（evaluated应改为evaluate）。易错点：识别倒装虚拟语气结构。

正确答案：B
