Which of the following is the relatively most accurate method for dating of fossils?

Electron spin resonance method is relatively most accurate method for dating fossils. Electron spin resonance dating is a technique that can directly detect unpaired or odd electrons in atomic or molecular systems. In this technique, a static magnetic field and microwaves are used to observe the behavior of the unpaired electrons in the material being studied. The study of the behavior of the electrons in a sample gives information about the condition of the sample.
