   A pharmaceutical company wants to use AI to accelerate drug discovery by predicting the effectiveness of candidate compounds. The company has a large dataset of molecular structures and their biological activity. The research team wants to identify promising compounds early to reduce R&D costs. However, the dataset is imbalanced, with very few active compounds compared to inactive ones. Which approach best addresses the data imbalance and the goal of identifying promising compounds?

   • AUse a generative model to create synthetic active compounds and add them to the dataset to balance it.
   • BTrain a standard classification model on the imbalanced dataset and rely on its overall accuracy to select compounds.
   • CUse a random undersampling technique to balance the dataset by removing inactive compounds, then train a standard model.
   • DUse a cost-sensitive learning approach that assigns a higher cost to misclassifying active compounds, and evaluate the model using precision-recall curves.
