Explanation

Machine Learning (B) is correct because it is precisely the AI subfield focused on enabling computers to automatically acquire knowledge and skills from data, improving their performance without being explicitly programmed - matching the question's description of "self-improvement through automatic knowledge acquisition."

Why the distractors are wrong:

• A (Expert System): An expert system encodes human knowledge manually through hand-crafted rules; it doesn't learn autonomously - a human expert must program the knowledge in.
• C (Neural Network): Neural networks are a technique used within machine learning, not a standalone research branch - they are a tool, not the field itself.
• D (Natural Language Processing): NLP focuses on enabling computers to understand and generate human language; it's a separate AI subfield, not concerned with general knowledge acquisition or self-improvement.

Memory tip: Think of the word "learning" - the question's phrase "automatically acquire knowledge and skills" is essentially a definition of learning. Machine Learning = machines that learn on their own.
