1. What are the steps to optimize the use of Amazon Translate for a specific language pair in a machine learning pipeline?

A) Train a custom translation model using Amazon Translate, perform a sentiment analysis on the translated text, and evaluate the model's accuracy using a confusion matrix.
B) Use the batch translation feature to translate a large volume of text, perform text preprocessing, and evaluate the quality of the translated text using a BLEU score.
C) Use the batch translation feature to translate a large volume of text, perform text preprocessing, and evaluate the quality of the translated text using a BLEU score.
D) Create a custom language model using Amazon Translate, use transfer learning to improve the model's performance, and evaluate the model's performance using a test dataset.
