The technology used to study the crystal structure of rocks and minerals is X-ray diffraction.

Here's a step-by-step explanation:

1. A sample of the rock or mineral is finely ground and placed on a glass slide.

2. The slide is then placed in an X-ray diffractometer.

3. The machine directs X-rays at the sample, and the crystal structure of the rock or mineral causes the X-rays to diffract, or spread out, in specific patterns.

4. These patterns are then detected and recorded by the machine.

5. Scientists can analyze these diffraction patterns to determine the crystal structure of the rock or mineral.

So, the correct answer is X-ray diffraction.
