Answer : The correct statement is The half-life of C-14 is 5,730 years.Explanation :The statement "After he dies, an agency of the body following the intake of C-14." is not correct because after an organism dies, its body stops to take the C-14. In place of the already absorbed C-14 starts decaying into N-14.The statement of "Radiocarbon dating is useful for dating objects of up to 100,000 years old." is not correct because Radiocarbon dating is the technique useful for dating objects up to 50000 years, because after that it completely breaks down. The oldest objects that are evaluated using the technique of Absolute Dating.The statement of "Radiocarbon dating assumes that the half life of a radioisotope to change with the time." is not correct, because the half-life of a radioisotope does not change, but remains constant therefore the statement that is true is "The half-life of C-14 is 5,730 years." which gives the correct half-life of C-14 isotope
