<span>The correct option is A. In nuclear fusion, two deuterium nuclei are fused together in the presence of high temperature and pressure to produce HELIUM NUCLEUS, neutron and energy. Very high quantity of energy is liberated during the process. Deuterium is a stable form of hydrogen and is found in water. </span>
Everything that we eat and drink contains some percentage of water. So, to start, you have to know that the human body has receptors which estimate if we have enough water in our blood and cells in general. From these receptors, the information travels through the neurons to the part of the brain that is responsible for activation of different responses.
The digestive system is important because in its lower parts, liquids are absorbed and inserted in the bloodstream. Then through the bloodstream, they travel to all parts of the body and are absorbed by cells as needed. When blood passes through the body, it gets to the kidneys where water and electrolytes are filtered, reabsorbed if needed and excreted through the urine.
Now, if the brain has a signal that the body has a lack of liquids, it activates hormones which influence the bloodstream in both the digestive and the urinary system. In this case, the digestive system will absorb more liquids from food because the hormones will make the blood vessels in the digestive area larger, and on the other hand, we will produce less urine because the kidneys will get an assignment from the brain to filter liquids, but to reabsorb them again as much as possible.
On land but close to oceans. Thus, option "A" is correct.
<h3>What is an earthquake?</h3>
Earthquakes occur as a result of collisions along oceanic-continental convergent boundaries.
The majority of the earthquakes occur alongside the Ring of Fire of the Pacific Ocean. The Ring of Fire is found in the basin which is a land area found close to the coastlines of the ocean. This validates its occurrence on land but close to the oceans.
Thus, option "A" is correct.

Relative dating best helps determine fossil age. It's where layers of sedimentary rock and fossils pile up on top of each other; the oldest fossils being in the bottom layer and the youngest in the top.
