To solve this question, we must apply the Multiplicative Principle. Let's analyze each element of the question: 1. 5 different shades. 2. 2 types of creaminess. 3. 3 types of skin. In addition, all foundations in the first batch will contain sunscreen, so we do not need to consider this variable in the calculation, as there is no option without sunscreen. Now, we apply the Multiplicative Principle by multiplying the options of each element: 5 shades x 2 creaminess x 3 types of skin = 5 x 2 x 3 = 30 different types of foundations. Therefore, the correct answer is "30".
