Answer 1

The correct option is A 1- Liquid

Water has the fluidic property and it takes the shape of the container it is kept in, a property shown by liquids.

Each sand grain is a solid particle which is a piece from broken rocks. Each sand grain has a fixed shape and volume. It is a solid.

When we squeeze a sponge, it changes shape but returns to its normal shape when we let go of the force. It has a definite shape. So, it is a solid.
