During metaphase, the alignment and attachment of chromosomes to the spindle fibers are crucial for proper cell division. At this stage, chromosomes are attached to the spindle fibers by their **kinetochores**.

### Explanation:
1. **Kinetochore**: This is a protein complex that forms at the centromere of a chromatid, where spindle fibers attach. The attachment allows the chromosomes to be moved to the cell's equatorial plane, ensuring each daughter cell receives the correct number of chromosomes.

2. **Centromere**: While the centromere is the region of a chromosome where the two sister chromatids are joined, it is the kinetochore structure that operates for attachment to the spindle fibers.

3. **Satellites** and **Secondary Constrictions**: These are additional structural features of certain chromosomes and do not play a direct role in the attachment during metaphase.

In conclusion, the correct answer to your question is that chromosomes are attached to the spindle fibers by their **kinetochores** during metaphase.
