You are developing an AI text generator that will be able to dynamically adapt its generated responses to mirror the writing style of the user and mimic famous authors if their style is detected. You have a large dataset of various authors' works, and you plan to host the model on a custom VM. You want to use the most effective model. What should you do?

A. Deploy Llama 3 from Model Garden, and use prompt engineering techniques. B. Fine-tune a BERT-based model from TensorFlow Hub. C. Fine-tune Llama 3 from Model Garden on Vertex AI Pipelines. D. Use the Gemini 1.5 Flash foundational model to build the text generator.
