What is the meaning of attempts in criminal law?

The term "attempts" in criminal law refers specifically to actions taken by an individual with the intention of committing a crime, even if those actions do not lead to the successful completion of that crime. Option A captures this definition accurately by describing attempts as "unsuccessful efforts to commit a crime."

In the context of criminal law, an individual can be charged with an attempt if they take substantial steps toward completing the criminal act, demonstrating both intent and a willingness to carry out the offense, even if they ultimately do not succeed. This concept underscores the legal principle that the law addresses both completed crimes and those actions that demonstrate a clear intention to commit a crime, highlighting the seriousness of the intent behind the act.

In contrast, the other options address concepts that are either unrelated or do not capture the essence of what constitutes an attempt in criminal law, such as a legal defense strategy, actions to avoid a crime, or repeated commission of a crime. Each of those elements pertains to different aspects of criminal behavior or legal proceedings rather than the specific definition of attempts.
