A company uses foundation models (FMs) to automate daily tasks.

Comprehensive and Detailed Explanation (AWS AI documents):

AWS Amazon Bedrock Prompt Management is designed to allow practitioners to create, version, store, and reuse prompts and system instructions when working with foundation models. It enables consistent reuse of contextual instructions across repeated interactions and applications.

Why the other options are incorrect:

Knowledge Bases store and retrieve external data, not reusable system instructions.

Guardrails enforce safety and policy controls, not prompt reuse.

Playgrounds are for experimentation and testing, not long-term prompt storage.
