What happens when a star like the sun exhausts its core hydrogen supply?
A) Its core contracts, but its outer layers expand and the star becomes bigger and brighter. B) It contracts, becoming hotter and brighter. C) It contracts, becoming smaller and dimmer. D) Its core contracts, but its outer layers expand and the star becomes bigger but cooler and therefore remains at the same brightness. E) It expands, becoming bigger but dimmer.
