__that he receives the admission notice from that uni A it islong before Bit is before long Cit won't be long before Dit will be before long

答案

答案应该是C,it won't be long before （that） he receives the admission notice from that uni...（不久他就会收到.的录取通知.）括号中的that是多余的.主句it won't be long 是将来时,从句before he receives the admission notice from that uni...用现在时.
其余三个答案都无法讲.
新年快乐!
