Explanation:

The app must:
Identify road signs and extract text from images
This is an OCR (Optical Character Recognition) task.
Azure AI Vision provides OCR capabilities to detect and extract text from images (including road signs).
Correct choice: Azure AI Vision.
Analyze the text to identify well-known locations
Once text is extracted, you need to detect if it refers to well-known places (e.g., cities, landmarks).
This is a Named Entity Recognition (NER) problem.
Azure AI Language service includes entity recognition for identifying locations, people, organizations, etc.
Correct choice: Azure AI Language.
Other options:
Azure AI Document Intelligence # Focused on structured documents (invoices, forms), not road signs.
Azure AI Search # Useful for indexing and search, not text extraction or entity recognition.
Correct Answer Matrix:
Extract the text # Azure AI Vision
Identify well-known locations # Azure AI Language
