The correct answer is: D. beatings
A beating is an act of hitting someone repeatedly, especially with the hands or a weapon. It is a form of physical violence that can cause serious injury or even death. In the context of the question, the police are denying that they have beaten people under their custody. This is a serious allegation, and it is important to investigate it thoroughly. If the police are found to have beaten people under their custody, they should be held accountable for their actions.

- Injuries are not necessarily caused by beatings. They can be caused by a variety of other factors, such as accidents or falls.

- Blunder is a mistake or error. It is not a serious enough offense to be the correct answer to this question.
- Excesses can refer to a variety of different things, such as overindulgence or going beyond what is acceptable. It is not a specific enough term to be the correct answer to this question.
