The correct answer is "interactions with light". Emission nebulae are caused by the interaction of energetic ultraviolet radiation from hot, young stars with surrounding gas, causing the gas to emit its own light. On the other hand, reflection nebulae are caused by the scattering of light off dust particles in space, reflecting the light from nearby stars and appearing as a bluish glow. Both types of nebulae can contain young stars and remnants of stars, but their distinguishing factor lies in their different interactions with light. The option "hard line edges" is not a distinguishing factor between emission and reflection nebulae.
