Answer:
The increasing order of conductivity is O< Ge< Mn.
Explanation:
Electrical conductivity is defined as the measure of the ability of a material to conduct electrical current through it. The conductivity depends on the atomic and molecular structure of the material.
Metals are good conductors because they have a structure with many electrons with weak bonds, and this allows their movement instead non-metals have between four and eight valence electrons, which lack this tendency.
The conductivity increases in the periodic table from top to bottom and from right to left.
oxygen is a nonmetal therefore it is a bad conductor.
Germanium is a metalloid whose conductivity is greater than a nonmetal and worst than a metal.
Manganese is a metal,in this case, it is a good conductor.
A cathode is the location in an electrolytic cell where reduction reactions take place.
An anode is the location in an electrolytic cell where oxidation reactions occur.
An electrolyte solution is any substance containing free ions that make the substance electrically conductive.

Because the concentration of molecules in the gas phase increases with increasing pressure, the concentration of dissolved gas molecules in the solution at equilibrium is also higher at higher pressures
The answer to the question is D.
