Rearrange the following sentences to form a coherent paragraph:
1. This makes them ideal for tasks like image recognition, natural language processing, and medical diagnostics.
2. Machine learning is a subset of artificial intelligence that focuses on the creation of algorithms that can learn from data without explicit programming.
3. The algorithm improves its performance by analyzing vast amounts of input data and identifying underlying patterns.
4. Instead of being given a set of rules, a machine learning model is trained on examples.

Correct option is A

Option (a) 2, 4, 3, 1 is the correct order of the given sentences.
Explanation (why this order is correct):
• 2 introduces the topic and defines machine learning—best opening.
• 4 logically explains the method: models are trained on examples, not fixed rules.
• 3 then explains what happens during training: performance improves by pattern recognition from large data.
• 1 concludes with applications: “This makes them ideal for…” refers to ML systems/models described earlier.
