The cloud has come to present the bright future of computing, a world where processing and storage become as (ubiquitous) and cheap as electricity.A. pervasiveB. feasibleC. continuousD. obvious

这道题考察的是词汇选择。题干中提到“processing and storage become as (ubiquitous) and cheap as electricity”，意思是“处理和存储变得像电力一样普遍和便宜”。我们需要找到一个与“ubiquitous”意思相近的词。选项中，“pervasive”意为“普遍的，无所不在的”，与“ubiquitous”意思相近；“feasible”意为“可行的”；“continuous”意为“连续的”；“obvious”意为“明显的”。因此，正确答案是A。
