The answer is; B
Rocks have naturally occurring and spontaneously radioactive atoms in them, such as carbon-14. These element isotopes decay into other types of atoms over millions of years. Therefore, by measuring the amount of these radiometric substances, and knowing the half-life of the isotopes, it is possible to postulate the age of a rock to within certain ranges of error.

Root anchor them in the ground and absorb water for the plant. Woody stem provides support to the plant and connect the roots and leaves. Leaves capture the sun's energy and use it to make food through the process of photosynthesis. Flowers contain the reproductive parts of the plant. fruite protect and help spread the seeds.
