请教大家一个语法点 947-281

iselibra

281.Even their most ardent champions concede that no less than a technical or scientific breakthrough is necessary before solar cells can meet the goal of providing one percent of the nation’s energy needs.
(A) that no less than a technical or scientific breakthrough is necessary
(B) that nothing other than a technical or scientific breakthrough is needed
(C) that a technical or scientific breakthrough is necessary
(D) the necessity for an occurrence of a technical or scientific breakthrough
(E) the necessity for a technical or scientific breakthrough occurring
答案是C，我选了A。
难到这里的no less than去掉不算改变了原意么？
怎么说no less than也代表了仅仅的意思

谢谢大家了
