Answer-first summary for fast verification
Answer: 300
In a 3-fold Cross-Validation combined with a grid search over a hyperparameter space, the total number of model runs is calculated by multiplying the number of folds by the product of the parameter values. Here, the parameter combinations are 2 (A) * 5 (B) * 10 (C) = 100. Multiplying by the 3 folds gives a total of 300 model runs.
