A company has built a chatbot that can respond to natural language questions with images.

Moderation APIs, such as Amazon Rekognition’s Content Moderation API, can help filter and block inappropriate or unwanted images from being returned by a chatbot. These APIs are specifically designed to detect and manage undesirable content in images.

Option A (Correct): "Implement moderation APIs": This is the correct answer because moderation APIs are designed to identify and filter inappropriate content, ensuring the chatbot does not return unwanted images.

Option B: "Retrain the model with a general public dataset" is incorrect because retraining does not directly prevent inappropriate content from being returned.

Option C: "Perform model validation" is incorrect as it ensures model correctness, not content moderation.

Option D: "Automate user feedback integration" is incorrect because user feedback does not prevent inappropriate images in real-time.
