Detailed explanation-1: -The correct answer will be option C. Mother tongue of a person will be categorical.
Detailed explanation-2: -The task of the regression algorithm is to map the input value (x) with the continuous output variable(y). The task of the classification algorithm is to map the input value(x) with the discrete output variable(y). Regression Algorithms are used with continuous data.
Detailed explanation-3: -Cross-validation is the best way to evaluate models used for prediction. Here you divide your data set into two group (train and validate). A simple mean squared difference between the observed and predicted values give you a measure for the prediction accuracy.
Detailed explanation-4: -Regression is a method for understanding the relationship between independent variables or features and a dependent variable or outcome. Outcomes can then be predicted once the relationship between independent and dependent variables has been estimated.
