To subtract binary numbers, you start from the rightmost digit and subtract the corresponding digits. If the subtrahend digit is greater than the minuend digit, you need to borrow 1 from the next higher digit. In this case:
```
1001 1110
- 0111 0010
-----------
0010 1100
```
There is a borrow operation during the subtraction of the second digit from the right, so the carry bit is 1. Therefore, the answer is B. 1.

MissingDependency: The 'whoosh' backend requires the installation of 'Whoosh'. Please refer to the documentation.
这个错误提示意味着你需要安装 'Whoosh' 模块来使用 'whoosh' 后端。你可以通过运行以下命令来安装它:
```
pip install whoosh
```
安装完成后,你需要在你的代码中导入 'whoosh' 模块,例如:
```
from whoosh.index import create_in
from whoosh.fields import *
```
然后,你可以使用 'whoosh' 后端来创建一个索引并搜索文本。不过在使用 'whoosh' 后端之前,你需要先了解一些关于它的基本概念和用法,可以参考 'Whoosh' 的官方文档:https://whoosh.readthedocs.io/en/latest/
