[ 3 4 6 8 12 ]

A : A single sorted array: [1 2 3 4 6 7 8 9 12 12 16]

B : You can't merge these two arrays, because they have different lengths.

C : Three arrays: [1], [2 7 9], [ 3 4 6 8 12 12 16]

D : A single array that alternates between the original arrays' elements: [1 3 2 4 7 6 9 8 12 12 16]
