Which best describes how the two-step method is used in capital punishment cases?

The answer is

A trial is held to decide guilt or innocence, and then a hearing is held to determine punishment.

When a capital punishment should be chosen, you first have the standard trial that determines whether or not the defendant is innocent. If proven guilty, a hearing is then made to determine the punishment, and after these 2 steps, you say whether or not he/she will be punished by death or not.
