Crescent? Really? Did they even read the question? That's gotta be the most random answer choice ever. *chuckles*

Jagged, definitely jagged. Who cares about the shape, I just want to pass this exam and get out of here! *sighs*

Hmm, I was thinking eyebrow, but now that I read it again, step-like does seem more accurate. Good thing I double-checked the question!

The interconnecting cracks between the blisters have a step-like appearance, so I'm going with option C. It just makes the most sense given the description.
