Understanding the Answer
Let's break down why this is correct
Matrix multiplication lets you combine rows and columns of numbers to create new data. Other options are incorrect because People think adding more features automatically improves models, but that is feature engineering, not a linear algebra operation; Logistic regression is a statistical method that uses linear algebra inside, but it is not an operation itself.
