The correct answer is A. abrasion, crystallization, pressure release.
Abrasion is the process of wearing away rock by the rubbing of other materials against it. This can happen by wind-blown sand, water currents, or glaciers.
Crystallization is the process of a substance forming crystals. This can happen when water evaporates from a solution, or when a gas cools. When crystals form, they can put pressure on the surrounding rock, causing it to break.
Pressure release is the process of rock being relieved of pressure. This can happen when a mountain range is eroded, or when a glacier melts. When pressure is released, rock can expand and break.
B. oxidation is the process of a substance combining with oxygen. This can happen when rock is exposed to the atmosphere. Oxidation can cause rock to break down and form new minerals.
C. carbonation is the process of a substance combining with carbon dioxide. This can happen when rock is exposed to rainwater. Carbonation can cause rock to break down and form new minerals.
D. thermal insolation is the process of rock being heated by the sun. This can cause rock to expand and break.
However, thermal insolation is not a major cause of physical weathering or mechanical rupture.
