Option 2: Rocks
Option 3: Trees
Option 4: 1 & 2
Correct Answer: 1 & 2
Solution : The correct answer is 1 & 2.
Carbon dating method is used to determine the age or rocks and fossil fuels. It measures the age of the material using organic content present in it. Carbon-14 is a radioactive isotope of carbon which is emitted by the fossils or rocks. The older the sample the less carbon-14 it would emit. When an animal dies it stops absorbing carbon and begins to disintegrate, so the age is calculated with the help of carbon-14 left in it.
