Unknown Puzzle: verticality

Below is the Unknown puzzle in its original form along with a doctored version. Does "D" seem a more appropriate answer in the doctored version?

ORIGINAL:


DOCTORED:

The shape that comes next has three qualities: 9; vertical mirror (as shown by "1"); style. Both A and D fit two of these three criteria, but the criteria are hierarchical, and only D meets the first two. The second image attempts to reinforce this hierarchy.
