Answer:
Water displacement is usually the method most students use because if you do it correctly, it can be more accurate than measurement and calculation.
Explanation:
If the object has an abnormal shape, you might be unable to measure its physical dimensions accurately. Instead, what you can do is measure the volume which is displaced when the object is immersed in a liquid or a gas. This is a very common method for measuring volume, and when done correctly, it is highly accurate.
For example, if you want to know the volume of a piece of ginger root, you can fill a beaker or a measuring cup with a known volume of water – let's say one cup. Next, add the ginger. Make sure that it is submerged underwater. Then, measure the new volume at the water line. The new volume will always be more than the starting volume. Subtract the starting volume (one cup) from this new volume, and you will have the volume of the ginger.
Option B is a balanced equation and follows the Law of Conservation of Mass. This is because the number of atoms of each element on both sides are the same.
