Question is slightly misleading

When one looks at the dark craggy vistas in Hitoshi Fugo’s evocative photo series, one’s mind might wander off to the cratered surfaces of faraway planets. ______ it’s the series’ title, Flying Frying Pan, that brings one back to Earth, reminding the viewer that each photo is actually a close-up view of a familiar household object: a frying pan.

 

Which choice completes the text with the most logical transition?

 

The passage presents "far away planets" in the first sentence, then it uses the phrase "back to Earth" in the second. These are two separate types of imagery, opposed to each other, so a disagreement transition like "but" or "although" would appear to work here. In fact, using the steps covered in the video, we arrived at such an answer. What does the community think?
