One single covalent bond, hope this helps!
Because water is polar and oil is nonpolar, their molecules are not
attracted to each other. The molecules of a polar solvent like water are
attracted to other polar molecules, such as those of sugar. This explains
why sugar has such a high solubility in water. Ionic compounds, such
as sodium chloride, are also highly soluble in water. Because water
molecules are polar, they interact with the sodium and chloride ions.
In general, polar solvents dissolve polar solutes, and nonpolar solvents
dissolve nonpolar solutes. This concept is often expressed as “Like
dissolves like.”
So many substances dissolve in water that it is sometimes called
the universal solvent. Water is considered to be essential for life
because it can carry just about anything the body needs to take in
or needs to get rid of.
There is no picture so I can't say the answer please update your post with the image BECUASE all non metals are located in the same group in the periodic table
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Oxidizing agent is the agent which oxidizes the other substance and itself gets reduced. It undergoes reduction reaction in which, it gains electrons and also the oxidation state of the substance gets reduced.
Reducing agent is the agent which reduces the other substance and itself gets oxidized. It undergoes oxidation reaction in which, it looses electrons and the oxidation state of the substance is increased.
For the given chemical equation:

Half reactions for the given chemical reaction:

Copper is loosing 2 electrons, thus it is undergoing oxidation reaction and is considered as a reducing agent.

Silver ion is gaining 1 electron per atom, thus it is undergoing reduction reaction and is considered as an oxidizing agent.
Hence,
is considered as an oxidizing agent and therefore the correct answer is Option B.
