The correct answer is:
d) The cube has a smaller surface area.
A cube of sugar has less surface area exposed to the water compared to granular sugar, which is made up of many smaller particles with a greater total surface area. The larger the surface area of the sugar, the more contact it has with the water, allowing it to dissolve at a faster rate.
