What constitutes a felony when associated with obstructing an officer?

The concept of a felony associated with obstructing an officer involves actions that significantly impede law enforcement's ability to perform their duties. Among the options provided, threatening future harm exemplifies a severe level of interference. This action goes beyond mere non-cooperation; it introduces an element of intimidation or potential violence directed at the officer or the process, justifying a felony charge. This can be interpreted as a direct challenge to the authority of law enforcement, as it not only obstructs the officer but also poses a risk to their safety.

The other options, while possibly contributing to an obstructive situation, do not carry the same weight in terms of legal consequences. Being uncooperative or refusing to answer questions may hinder an investigation but typically does not rise to the level of a felony. Attempting to run away can complicate situations and may result in charges, but it is generally treated more as a misdemeanor unless accompanied by additional threatening behavior. Thus, the correct answer reflects an understanding of how severe and threatening actions towards law enforcement are treated under the law.
