Answer:
Option (c) is correct.
Step-by-step explanation:
The density of a substance is 0.83 g/mL.
We know that the density of water is 1 g/mL
It means the density of the substance is less that that of density of water. If the density of substance is less that water then it will float on water's surface.
Hence, the correct option is (c) "The substance will FLOAT because it's density is SMALLER than water".
