Explanation

GitHub Copilot Chat has two notable limitations reflected in these answers. (A) Limited training data: Copilot's model has a knowledge cutoff and was trained on a finite corpus of public code, meaning it may lack awareness of newer libraries, frameworks, or niche languages - this is a genuine limitation. (D) Extensive support for all programming languages is actually NOT true, which is why it is listed as a limitation - Copilot performs significantly better in mainstream languages like Python, JavaScript, and TypeScript than in less common ones. Option B ('Ability to handle complex code structures') is not a standard limitation - Copilot can handle complex structures reasonably well. Option C ('No biases') is incorrect as a limitation statement; bias in suggestions IS a real concern, meaning the absence of bias cannot be claimed.
