Explanation

This problem tests the fundamental counting principle, which states that the total number of choices is equal to the product of the independent choices. Therefore, the total number of tacos is (3) (4)(3)(5) = 180 tacos.

Using the combination rule we can have such representation : 3C1*4C1*3C1*5C1 = 3*4*3*5 =180 tacos
