Many people are not fully aware of the damage that it does to their health. This is ____ we chose this picture as our logo.

A．that	B．because
C．why	D．for which

答案

C

解析

试题分析:句意：许多人没有充分意识到它对健康的损害。这就是我们为什么要选择这张图片作为我们的徽标。Is后面是表语从句，根据前后句意可知此处表示结果，固定句型：this is why+从句“这就是为什么……”，this is because+从句“这是因为……”，答案选C。
