Which of the following best describes the action of 'abet'?

The action of 'abet' means to actively support or assist someone, particularly in the context of encouraging or helping them carry out an action, which is often illegal or unethical. This term is commonly used in legal contexts where an individual may assist another in committing a crime, but it can also apply more broadly to any supportive role that leads to a particular outcome.

In this case, the correct choice emphasizes the proactive nature of abetting—it's not just about providing passive support or overlooking an issue; it involves a level of engagement that helps in executing a specific action. Hence, it encapsulates the essence of 'abet' as being more than mere encouragement—it's about taking affirmative steps to facilitate someone's actions.
