Choose the correct explanation of how do red giants manufacture carbon-rich dust grains, and why are these important to life?1. The convection in a low-mass star in its final stages of life dredges up carbon from the core and brings it to the surface. Because the carbon can then be lost via the stellar winds, these stars seed the interstellar medium with carbon, including the carbon that is used for life on Earth. 2.
