I would choose A because you can see some of the inner workings.

Option A is a more intriguing image, because it shows me some of internal mechanisms of the door handle and also shows how it will look from both sides. I like how it has a simple push-button lock on the inside, so I would click on A to learn more about how it fits and how it should be installed.

A actually shows off the lock and locking mechanism and detail, while B just demonstrates it in action, obscuring much of it with a hand unfortunately.

this is the most clear to me that it can be a vacant or occupied door handle with the visual in use with B

Too much white space with A. I think B is a better presentation.

I like B best because it shows the product in use, which I think gives a better idea of how it can be used.

Option B seems more realistic to me. Of course, Option A shows the actual product, but it doesn't look the same way it would after it was installed and was in use.

I prefer the product photo in option B because it shows the "vacant" side of the door handle. I don't know why you would show the inside part of the handle with the "vacant" part in a small thumbnail.

I would click on B first because it looks more presentable. You can see it being used and don't have to see the inside of the prouduct. I also like the way the "vacant" looks on it.

Seeing it as it would be utilized is more relevant than just the hardware alone.

This image shows how easy the product is to use and exactly how it looks.

I get a better idea of what this looks like and how it works in this image.

Choice B because I can see how the door handle works in a natural setting and not just a white background.

I like how B shows how it works better.

The product looks most professional and understandable in this image.
