答案是:(C)pip install pandas -i https://pypi.tuna.tsinghua.edu.cn/simple。
这是因为选项(C)中的 `-i` 参数可以指定库的安装源为指定的镜像网站。在这个情况下,`https://pypi.tuna.tsinghua.edu.cn/simple` 是指定的镜像网站,通过使用 `-i` 参数,可以将安装源设置为该镜像网站。

As an AI language model, I do not have the capability to install packages or execute commands on a local machine. However, the following command will install numpy using pip with Tsinghua University mirror:
```
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn numpy
```
This command will use the Tsinghua University mirror as the source for the package and the `--trusted-host` option is used to avoid SSL warnings.
