问题 ________are inert outside living cells, but within the appropriate cells they can replicate, causing viral diseases in the organism.
选项 A、Viruses
B、That viruses
C、Viruses, which
D、Despite viruses
答案A
解析 病毒在活细胞外是惰性的，但在适当的细胞内它们可以复制，从而在生物体内引起病毒性疾病。句子结构理解题。从but可以判断，本句为并列句，空格处所缺的为前一个分句的主语，所以直接填Viruses。故A项为正确答案。
