Text Moderation API is correct because the response from that service returns a list of potentially unwanted words found in the content and it indicates which categories of unwanted words were detected as well as any possible personally identifiable information located in the text.

The Text Moderation API is intended for content moderation workflows and it provides matched terms and category labels that help callers decide whether to block, flag, or redact content. The API is therefore the best fit for the description in the question.

Cloud Data Loss Prevention API is incorrect because that service focuses on detecting, classifying, and transforming sensitive data such as PII for data protection and redaction rather than providing a moderation-style list of unwanted words and category labels for policy enforcement.

Content Filter API is incorrect because that name is a generic term and does not match the documented Summit Cloud service that returns categorized unwanted-word matches and PII hints. The question expects the specific product name which is the Text Moderation API.

Text Filter API is incorrect because it is not the documented name of the service described. The described behavior maps to the Text Moderation API rather than a differently named filter API.
