B.Bismuth
C.Copper
D.Antimony

Answer 1

Here, the word deposits is used with silver which means the deposits of silver and deposits are basically the concentration of minerals that is present in the crust of the earth, naturally. And silver is an element with $Ag$ as it’s symbol.

Complete answer:
Before finding out the answer of this question, let’s understand first what deposits are and what kind of element silver is.
Deposits are nothing but the natural occurrence of elements which are present in the crust of the earth. Now let’s understand what silver is. Well, we know what a periodic table is, in periodic table all the known elements are present in the tabular form with their properties. Similarly, silver is also an element which is present in the periodic table with $Ag$ as a chemical symbol and $47$ as its atomic number.
Now let’s understand what silver deposits are. Silver is present in the form of a compound in the crust of the earth. $0.08$ parts per million is the abundance of the silver in the earth’s crust which is similar to the abundance of the mercury which is denoted by the chemical symbol $Hg$.
Now, let’s see what is found in the deposits of silver. So, the correct option for this question is Option C- Copper. Copper is an element with $Cu$ as a chemical symbol and with atomic number $29$. It has red-orange coloured metallic lustre and $63.546$ as an atomic mass.
Therefore, the correct answer is option C.

Note:
Copper has several applications and the major applications are electrical wire- copper wires are used for several purposes such as in the generation and transmission of power, etc. and some other applications are plumbing and roofing and also in the machineries present in industries, etc. These are not the only applications but have several other uses in several other fields.
