(A) The holographic displays are expensive to install and maintain
--> cost is irrelevant to the accidents

(B) Many other venues, including shopping malls, are considering adopting holographic displays
--> we can't conclude whether the usage of hologram by other venues would reduce or increase the distraction and accidents.

(C) Accidents in supermarkets that are serious enough to cause injury are rare.
--> still irrelevant, we are concerned with the accidents, not the injuries.

(D) Supermarkets tend to be low-margin businesses that struggle to achieve profitability.
--> profitability is irrelevant to the conclusion of concern

(E) Studies in test markets have shown that supermarket patrons quickly become accustomed to holographic displays
--> if patrons become quickly adapted, so displays will not be intrusive to them as claimed, and accidents will be less likely to happen (Correct)
