The lecture video stated that, for SVM$,$ it is desirable to transform the input data in a way that allows for separation by a straight line. Choose the most appropriate reason for this. Question $2$ Select one: a$.$ The data preprocessing to make it separable by a straight line is a fundamental aspect of data preprocessing in all classification problems, not just for SVM$.$ b$.$ SVM is a method that implicitly assumes that the data can be separated by a straight line. c$.$ SVM assumes a statistical model where the data originates from two normal distributions with equal variance.
