Community Insight
This question tests recognition of Amazon Lex as the conversational AI service; the trap is confusing it with other AI/ML or analytics services such as Textract, Rekognition, or Glue.
Amazon Lex is the AWS conversational AI service used to build chatbots and voice assistants. This page explains why Lex, not Textract, Glue, or Rekognition, satisfies the website chatbot requirement.
Test takers may choose Amazon Rekognition because it is also an AI service, but Rekognition analyzes images and video, not conversational text or speech.

Expert Analysis
Why the Answer Is Correct
Amazon Lex is the AWS service purpose-built for conversational interfaces, using automatic speech recognition and natural language understanding to create chatbots and voice assistants. A company can define intents, utterances, slots, and fulfillment logic in Lex and then invoke the bot from a website through AWS SDKs or APIs. The question's requirement is exactly a conversational chatbot, so Lex matches the core capability without requiring custom NLU infrastructure. Community learners consistently confirm this mapping: alokdixit2006 labels it "Conversational AI for Chatbots," and Yomijohnson notes it is "specifically designed for building conversational chatbots." ShaiTay and d00b229 also independently select "B. Amazon Lex."Why the Other Options Are Wrong
Amazon Textract is an OCR/document analysis service that extracts text, forms, and tables from scanned documents; it cannot hold a conversation. AWS Glue is a serverless data integration and ETL service used to discover, prepare, and move data for analytics, not to interact with website visitors. Amazon Rekognition analyzes images and videos for objects, faces, text, and moderation, so it may be an AI service but not a conversational one. None of these three options provides the intent handling and dialogue management that a chatbot needs. Therefore only Lex satisfies the scenario.Community Comment Notes
All visible votes are for option B, which reflects strong consensus rather than a contested answer. One learner spells out the product category as "Conversational AI for Chatbots," while another explains that Lex lets teams "create, deploy, and integrate chatbots into applications such as websites or mobile apps." The remaining comments simply confirm "B. Amazon Lex" without additional objections. There are no dissenting comments suggesting Textract, Glue, or Rekognition, so the community evidence aligns with the technical analysis. This makes the source key's suggested answer B reliable.Official Reference
Exam Strategy
When a question mentions chatbot, conversational interface, voice assistant, or natural-language understanding, map it to Amazon Lex. Eliminate other AI services by their input/output: Textract for documents, Rekognition for images and video, and Glue for ETL.
