正确答案
解析
此处考察上下语境下动介的搭配问题。文中提到People who perceived greater social support were less likely to come____with a cold。上文提到做实验研究受试者在接触病毒之后患感冒的易感性。题目涉及实验的结果，有着更大感知社会支持能力的人患感冒的几率更低。所以这里要填一个介词与come搭配，表示患上感冒。come down下来，降落;倒塌;感染。因此排除A.come across偶遇;偶然发现;使产生…印象;B.come along出现，发生，进展;D.come out出现;出版;结果是,都不符合语义。因此正确答案为C选项。
