The answer is Sentiment Analysis, which is the correct Azure AI Language feature for automatically classifying product reviews as positive, negative, or neutral. This feature uses prebuilt sentiment analysis for product reviews by analyzing the text’s emotional tone at both the document and sentence levels, assigning confidence scores to each sentiment label. On the Microsoft Azure AI Fundamentals AI-900 exam, this question tests your understanding of Azure AI Language’s prebuilt capabilities versus custom solutions like Custom Text Classification—a common trap is confusing sentiment analysis with key phrase extraction or language detection. A useful memory tip is to think of “sentiment” as the feeling behind the words, so if the task is to gauge opinion (positive, negative, neutral), Sentiment Analysis is always the go-to choice.

Detailed technical explanation
How to think about this question
Under the hood, Azure AI Language's Sentiment Analysis uses machine learning models trained on large datasets to assign a sentiment score (e.g., 0 to 1 for positive, negative, or neutral) at the document and sentence level. A subtle behavior is that it can handle mixed sentiments within a single review, providing both an overall score and per-sentence breakdowns, which is critical for nuanced product feedback. In a real-world scenario, a review like 'Great product but terrible customer service' would yield a mixed result, allowing the marketing team to drill down into specific aspects.
