Answer
C. BLEU
Explanation
The correct answer is C. BLEU. BLEU (Bilingual Evaluation Understudy) is a metric for evaluating the quality of text which has been machine-translated from one natural language to another. BLEU focuses on precision in matching generated output to the reference text by counting the number of n-grams (sequences of words) that are common between them. BLEU is widely used for text translation, as it correlates highly with human judgments of quality and is easy to understand and compute.
