The third one because
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

Answer: The correct option is C.
Explanation: Beta minus (
) decay is the decay in which a neutron is converted into proton and releases beta particle or generally known as electron.
There is an increase in the Atomic number because one protons is being formed.
In the case of beta-minus decay of phosphorous, the P-nucleus gets changed to Sulfur nucleus. The balanced Chemical equation for this process is:

Hence, the correct option is C.
Explanation:
Acidic Oxide
An acidic oxide reacts with water and produces an acid. Usually, it is the oxide of non-metals. Examples include SO2, CO2, SO3, Cl2O7, P2O5, and N2O5. It could also be the oxide of metals with high oxidation states, such as CrO3, Mn2O7, and V2O5.
