Consider the following code block and if needed make appropriate assumptions:
from sklearn.linear_model import LinearRegressionfrom sklearn.model_selection import cross_val_scorefrom sklearn.model_selection import ShuffleSplitshuffle_split = ShuffleSplit(n_splits=5, test_size=0.2, random_state=42)score = cross_val_score(estimator= LinearRegression(), X= X_train, y= y_train, cv= shuffle_split, scoring= '____________')Which of the following may be appropriate to be filled in the blank space value for scoring parameter?
