The change that would cause the sugar to dissolve faster is:
**b) Grind up the cube in granules.**
Grinding the sugar into smaller pieces increases its surface area, allowing for more contact with the water molecules, which enhances the rate of dissolution. The other options would either have no significant effect or hinder the dissolution process.
