Describe the process of model selection using cross-validation and grid-search. Include details on how to implement this process in a machine learning pipeline using Python and the scikit-learn library, and explain the benefits of this approach.
A
Model selection involves choosing the first model that shows acceptable performance without any further tuning.
B
Model selection using cross-validation and grid-search involves systematically testing different models and hyperparameters to find the best combination for the given dataset.
C
Model selection is a manual process that does not require any computational tools or libraries.
D
Model selection is only applicable to simple models and not to complex machine learning models.
