Which of the following is not Machine Learning?

Answer: Option B

Which of the following is not Machine Learning?

Option A: Artificial Intelligence
Artificial intelligence (AI) is a broad field that encompasses various subfields, including machine learning. Machine learning is a subset of AI. So, Option A is not the correct answer because AI includes machine learning.

Option B: Rule-Based Inference
Rule-based inference refers to making decisions or drawing conclusions based on predefined rules and logic. This approach does not involve learning from data, which is a core characteristic of machine learning. Therefore, Option B is the correct answer as it is not considered a part of machine learning.

Option C: Both A and B
As explained, artificial intelligence (Option A) includes machine learning, but rule-based inference (Option B) is not considered a part of machine learning. Therefore, Option C is not the correct answer.

Option D: None of the Mentioned
Since at least one of the options (Option B) is not considered a part of machine learning, Option D is the correct answer.

In summary, rule-based inference (Option B) is not a component of machine learning, making Option B the correct choice.
