C
Train a new FM.
D
Use prompt engineering.
✓ Correcta
Explicación
Prompt engineering is the most cost-effective solution for improving the accuracy of FM responses. It requires no model training or additional compute costs — just crafting better prompts. Fine-tuning, retraining, or training a new FM are all significantly more expensive options.
