The correct answer is A. works for both sides.
To cut both ends means to try to benefit from both sides of a situation. This can be done by working for both sides of a conflict, or by arguing in support of both sides of an issue. It can also be done by taking advantage of both sides of a situation, such as by buying from one side and selling to the other.
Option B is incorrect because arguing in support of both sides of an issue does not necessarily mean that someone is working for both sides. It is possible to argue in support
of both sides of an issue because one believes that both sides have valid points.Option C is incorrect because behaving dishonestly does not necessarily mean that someone is trying to benefit from both sides of a situation. It is possible to behave dishonestly for other reasons, such as to gain an advantage over someone or to cover up one’s mistakes.
Option D is incorrect because creating discord among friends does not necessarily mean that someone is trying to benefit from both sides of a situation. It is possible to create discord among friends for other reasons, such as to get revenge on someone or to simply cause trouble.
Option E is incorrect because inflicting injuries on others does not necessarily mean that someone is trying to benefit from both sides of a situation. It is possible to inflict injuries on others for other reasons, such as to hurt someone or to defend oneself.
