Last week local shrimpers held a news conference to take some credit for the resurgence of the rare Kemp's ridley turtle, saying that their compliance with laws requiring that turtle-excluder devices be on shrimp nets protect adult sea turtles.

A.requiring that turtle-excluder devices be on shrimp nets protect

B.requiring turtle-excluder devices on shrimp nets is protecting

C.that require turtle-excluder devices on shrimp nets protect

D.to require turtle-excluder devices on shrimp nets are protecting

E.to require turtle-excluder devices on shrimp nets is protecting


（B）


我选了（A）


我有两个疑问，第一个是为什么这里require后面的that可以省略。 第二个是require that 后面不是必须跟虚拟语气的吗？


求解答，万分感谢

谢谢你的解答，但是B选项是一个完整的句子，而不是sth。

有没有人知道呢，白用语法上说，require that必须虚拟来着
