Given the code snippet and assume if any necessary requirements: from sklearn.model_selection import GridSearchCV from sklearn.linear_model import LogisticRegression param_grid = {'C': [0.1, 1, 10], 'penalty': ['l1', 'l2'], 'solver': ['liblinear']} clf = GridSearchCV(LogisticRegression(), param_grid, cv=5) clf.fit(X_train, y_train) print(clf.best_params_) What does cv=5 signify in this context?

(B) The model is trained and evaluated using 5-fold cross-validation for hyperparameter tuning

(A) The training data is split into 5 different datasets, each used to train a separate model.

(C) Five different models are trained on 5 resampled datasets of training data.

(D) The dataset is divided into 5 parts and trained in a single pass without cross- validation.

+2 marksOne correct option

Given the code snippet and assume if any necessary requirements:

python

1from sklearn.model_selection import GridSearchCV
2from sklearn.linear_model import LogisticRegression
3param_grid = {'C': [0.1, 1, 10],
4              'penalty': ['l1', 'l2'],
5              'solver': ['liblinear']}
6clf = GridSearchCV(LogisticRegression(), param_grid, cv=5)
7clf.fit(X_train, y_train)
8print(clf.best_params_)

What does cv=5 signify in this context?

A
The training data is split into 5 different datasets, each used to train a separate model.
