Which of these properties gives a solid its definite shape?

A solid's definite shape is due to its strong intermolecular attraction. In solids, the molecules are tightly packed together and have strong forces of attraction between them. These forces keep the molecules in a fixed position and prevent them from moving around freely. As a result, solids have a definite shape that is maintained even when the solid is subjected to external forces. In contrast, liquids and gases do not have a definite shape because their molecules have weak intermolecular forces and can move around more freely.
