Final answer:
Option 2,3.
Major essential minerals, such as calcium and phosphorus, are found in large amounts, while trace essential minerals, like iron and copper, are found in smaller amounts. Arsenic's role in human biology is not well-defined and may require further clarification.
Step-by-step explanation:
The classification of minerals includes major essential minerals and trace essential minerals. Major essential minerals, such as calcium and phosphorus, are present in large quantities in the human body, primarily stored in the skeleton and necessary for bone health.
On the other hand, trace essential minerals, like iron and copper, are needed in much smaller amounts and are still critical to body functions, with iron being instrumental in the formation of hemoglobin.
It is not entirely true that minerals like arsenic are not necessary for human biological function.
While some elements may be toxic in high amounts or not traditionally recognized as necessary, research has suggested that in trace amounts, elements that were once thought to be non-essential might play a role in human biology.
As per the information provided and to correctly answer your query, Statement 2) 'Major essential minerals are present in the body in large amounts,' and Statement 3) 'Trace essential minerals are present in the body in small amounts' are true.
As for Statement 1) concerning arsenic's biological necessity, it would not be considered a 'major' or 'trace' essential mineral, and therefore, the statement as it stands might require clarification.
