The code defines an array of integers, [4, 7, 11], and calls the forEach method on it, passing in the stepUp function. The stepUp function takes three arguments: the value of the element, its index, and the array itself. In this case, stepUp returns the value plus one, so the forEach method modifies the original array by adding one to each element. The resulting array is [5, 8, 12]. Therefore, the correct choice is C.
