Correct Answer:
B. Python
The correct answer is Python. Python is currently the most widely used programming language in Artificial Intelligence (AI) and machine learning. Its popularity is due to its simplicity, extensive libraries (like TensorFlow, PyTorch, Scikit‑learn, and Keras), and strong community support. Among the options:
- C++: Used for performance-critical AI applications but not as widely adopted for general AI development.
- Python: Correct; it is the dominant language in AI today.
- Java: Used in some AI applications but not as popular as Python.
- HTML: A markup language for web pages, not a programming language used in AI.
Therefore, the correct answer is "Python".
