Correct answer: C. Habit
- A. Characteristic
- B. Symmetry
- C. Habit
- D. All of these
Explanation
Crystal habit is the characteristic external shape of an individual crystal or crystal group. The habit of a crystal is dependent on its crystallographic form and growth conditions.So, Definite Shape of NaCl crystal is its habit

About Shape of Ionic Crystals
Ionic crystal shape depends on the regular arrangement of oppositely charged ions in a three-dimensional lattice. The topic covers coordination number, radius ratios, lattice geometry and structures such as sodium chloride, caesium chloride and zinc sulfide, which should not be confused with the molecular shapes predicted by VSEPR theory.
