Right option is (c) 12 grams

To elaborate: A sample of 12 grams of carbon is equal to one mole. The amount of moles in a substance can be determined using that substance’s molar mass. The molar mass is the amount of grams in one mole of a substance. The molar mass is the average atomic mass for a substance.
