I will give 25 points and make them brainlest if they solve this. A carbon atom that is a part of your body could very well have been part of a dinosaur millions of years ago. What BEST explains this?

A The carbon atoms that are found in current living things are developed when the organism is produced.
B Carbon atoms found in current living things are the same carbon atoms that have always been a part of living things, they are just recycled.
C This could not be explained because carbon found in our bodies could not have a part of any previous organism.
D Carbon atoms are genetically passed through the evolution of organism.
