The correct response is:

**Supernovae that are moving away at an accelerating rate**

Evidence for dark energy primarily comes from observations of distant supernovae, specifically Type Ia supernovae, which appear to be receding from us at an accelerating rate. This acceleration suggests that there is a form of energy (dark energy) causing the cosmic expansion to speed up.
