b. Machine learning
Explanation:
The technique that is being described in this situation is known as Machine Learning. This is a fairly new technology that has become popular over the last decade. Machine learning uses artificial intelligence to analyze data and learn from it. Every time the system analyzes the data it learns something new, saves it, and implements it to its processes. Therefore, the more times it repeats the more it learns. These systems are continuously getting better and learning more, which makes them incredibly efficient.
