The science of using tree rings to determine absolute age is called

a. disconformity.

b. radiometric dating.

c. dendrochronology.

d. radioactive dating.

Option c. dendrochronology

tree rings or dendrochronology they allow to use it in calibration for carbon-14 on temporal placements of fragments of wood (from long dead trees).

Example Bristle cone pines (1957) 4723 years old

The best answer to the question that is being presented above would be letter c. Dendochronology is the science of using tree rings to determine absolute age. All the others are other forms of dating that would determine the tree's age.
