Which sentence is most clearly written?

The sentence that stands out as clearly written uses a direct and straightforward approach. It states that the officers brought the case to a successful conclusion, which is not only concise but also directly attributes the action to the officers. This clarity helps to convey the message without any unnecessary complexity or added phrases.

In contrast, the first sentence employs a more roundabout construction. Phrases like "were involved in bringing" introduce additional words that can dilute the impact of the statement. By making the sentence longer and more complicated, it can lead to ambiguity about the officers' role. The second sentence's directness eliminates any potential confusion about what the officers did, making it the superior choice for clarity.
