<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or
radioactive dating is used, for example, rocks or carbon, in which trace
radioactive impurities were specifically fused when they were framed. The
strategy looks at the abundance of a normally happening radioactive isotope
inside the material to the abundance of its decay items, which shape at a known
consistent rate of decay.</span>
