Answer:
sponge is not a true solid
Explanation:
spongesponge is considered as a solid but by the property of solid of negligible compressibility sponge is a solid which is highly compressible hence it can not be considered as true solid
rubber band can also be considered as not a true solid as it is also compressible and has the ability to store energy by the property of elasticity, but it returns back to its original form when other external force is remove
so in this case the correct answer should be sponge
