A company wants human-labeled data to fine-tune a foundation model but does not want to build labeling tools or manage a labeling workforce. Which AWS service provides that capability?

Amazon SageMaker Ground Truth Plus is the correct answer because it is a fully managed data labeling service that handles the entire labeling workflow, including hiring and managing the labeling workforce, and building and maintaining labeling tools. This directly addresses the company's need to fine-tune a foundation model with human-labeled data without managing the labeling process themselves. Amazon SageMaker Data Wrangler is incorrect because it is used for data preparation and feature engineering, not for managing human data labeling. Amazon Transcribe is incorrect as it is an automatic speech recognition service, converting audio to text, which is not relevant to human data labeling for fine-tuning. Amazon Macie is incorrect because it is a data security and privacy service that discovers and protects sensitive data, unrelated to data labeling.
