C is the correct answer
The ROUGE (Recall-Oriented Understudy for Gisting Evaluation) score is widely used to measure the similarity between generated text and a set of reference texts. Since the company wants the LLM's output to resemble the provided readable examples, ROUGE is the most appropriate metric. ROUGE compares the LLM-generated text with the human-provided reference texts by evaluating n-gram overlap, precision, recall, and F1 score, making it a great choice for text coherence and readability assessment.
The correct answer is C. ROUGE score measures how well generated text matches reference examples.
