Answer:
B) Radiometric dating
Explanation:
Radiometric dating: Is a method used to date material such as rocks or fossil by comparing its radioactive isotope material contained in it with the amount of it's decay products. Since the decay occurs at a constant rate Scientists/Geologists are able to obtain it's relative age.

Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL
