Answer: We have 12 combinations of protein and sauce.
Explanation:
For protein, we have 4 options (beef, pork, chicken, and tofu)
For sauces, we have 3 options (hot, tangy and sweet)
The number of combinations is equal to the multiplication for the number of options for each selection.
Combinations = 4*3 = 12
