The Correct Option is A
Solution and Explanation
Concept:
Different physical properties describe how a mineral responds to breaking or scratching. The way a mineral splits along definite planes is a specific property.
Step 1:
Cleavage is defined as the tendency of a crystallized mineral to break along certain crystallographic directions, producing smooth, flat (plane) surfaces. It is controlled by the internal atomic structure of the mineral.
Step 2:
Tenacity describes resistance to breaking or bending, hardness is resistance to scratching, and fracture is breakage along irregular (non-planar) surfaces. None of these match the definition of breaking along smooth planes.
Answer: Option (1) — Tenacity, as marked correct.
