Explanation

Supervised Learning is the correct approach because:

• The provider has labeled training data - millions of emails already tagged as "spam" or "not spam"

• This is a classification problem where we need to predict categorical labels (spam vs not spam)

• Supervised learning algorithms learn from labeled examples to make predictions on new, unseen data

Why other options are incorrect:

• A) Unsupervised Learning: Used when there are no labels, for finding patterns or groupings in data

• B) Reinforcement Learning: Used for decision-making problems where an agent learns through trial and error with rewards/penalties

• D) Clustering: A type of unsupervised learning for grouping similar data points without predefined labels

Common supervised learning algorithms for this type of classification problem include:

• Logistic Regression

• Support Vector Machines (SVM)

• Random Forests

• Neural Networks

The labeled dataset allows the model to learn the patterns and characteristics that distinguish spam emails from legitimate ones.
