Selected Answer: D
The first sub-array in the output array contains the first indices of the input sub-arrays. The second index contains the second indices of the inputs, the third contains the third indices, and so on for every case where there are the same number of indices in the arrays. https://docs.mulesoft.com/dataweave/2.4/dw-core-functions-zip
