Given statement: Decisions about handcuffing or restraining inmates are often left to the officers involved. An officer is legally responsible for exercising good judgment and for taking necessary precautions to prevent harm both to the inmate involved and to others. 

The situations in which handcuffing or physical restraint is most likely to be needed is→ An inmate seems to have lost control of his senses and is banging his fists repeatedly against the bars of his cell.

In this situation inmate's behavior indicates a potential risk to both themselves (due to possible injury from banging against the bars) and others. If an inmate loses control of their senses, it could possibly be a sign of a medical emergency, agitation, or violence, making it necessary to restrain them to prevent harm.

Hence, "Option 1" is the correct answer.
