D. The existence of a fracture zone is "Points X and Y are slowly moving in the same direction, showing that line 2 is a fracture zone".
<h3>
What is fracture?</h3>
A fracture is any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces.
<h3>Characteristics of fracture zone</h3>
Ocean crust in a fracture zone looks like it has been sliced up by a giant knife.
The faults usually cut across ocean ridges, often nearly at right angles to the ridge.
Thus, based on the information given, the data that would provide evidence of the existence of a fracture zone is "Points X and Y are slowly moving in the same direction, showing that line 2 is a fracture zone".
