What is true about the stars as observed from the Earth's Equator?

The correct answer is that all stars rise and set as the celestial sphere rotates. Observing from the Earth's Equator, you are positioned such that celestial objects appear to move vertically across the sky. The rotation of the Earth causes stars to be visible as they rise above the horizon and then set below it throughout the night.

At the Equator, observers have a unique perspective where they can see the full range of celestial objects, including stars from both the northern and southern hemispheres, as most stars will have the opportunity to rise and fall within their observable sky. This results in a diverse assortment of stars visible throughout the night.

Other options do not align with the general observation from the Equator. For instance, the concept of circumpolar stars is limited to regions closer to the poles, where some stars do not rise or set but instead remain visible all night. Saying no stars are visible contradicts the reality that a plethora of stars can be seen at the Equator. Similarly, stating that only a few stars are visible downplays the richness of the night sky from that vantage point.
