C是正确答案.
It be essential that 后面一定用虚拟语气,且句子谓语动词固定为(should) + 动词原型
类似还有
it is +necessary等形容词后,that主语从句中虚拟形式使用,这类形容词包括necessary,important,essential,imperative,urgent,preferable,vital,advisable等,例如It is necessary that you listen to the teacher carefully.或者It is essential that you be able to pronounce every single word correctly.
