The correct answer is A. Fracture
Explanation:
A fracture occurs when a mineral, for example, calcite or quartz breaks in an irregular pattern. Fractures can occur due to multiple factors including pressure, temperature, among others. Additionally, fractures the term "fracture" differs from the term "cleavage" because in fractures breaks are irregular while in cleavage minerals break in a definite structure along the structural planes of the mineral. Thus, a fracture is the irregular break of a mineral.
