It is True, oxidation is associated with an increase in oxidation number.
An oxidation; reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Oxidation states are typically represented by integers which may be positive, zero, or negative.
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.

Option C:
The magma's cooling rate determines the size of crystals that are formed.
Explanation:
Once magma erupts from a volcano to the surface of the earth, it begins to cool because of the relatively cooler temperatures at the surface of the earth.
The magma usually cools down to form igneous rocks on the surface of the earth. The rate at which the magma cools down determines the size of the rock crystals that are formed.
If the magma cools slowly, there is enough time for crystal growth within the rock particles. This gives rise to larger rock crystals.
If the magma cools rapidly, there is little time for crystal growth. This leads to the presence of smaller rock crystals.
