5. B
解析
【分析】这道题考查be动词的用法，解题时需先明确主语的单复数，再匹配对应的be动词形式。句中主语是指示代词These（这些），指代复数概念，且后面接了两个并列的名词（a carrot和green beans），整体为复数含义，因此要选择对应的复数be动词。
【解析】句子主语是指示代词These，表复数，后面的“a carrot and green beans”是两个并列的名词，属于复数概念，所以be动词需用复数形式are，对应选项B。
【答案】B
【知识点】be动词的用法；主谓一致
【点评】本题是英语基础题，结合指示代词的复数属性和并列名词的单复数，即可快速判断be动词的形式，难度较低。
【难度系数】0.8
