A pebble that sinks in water has greater density than a twig floats on top of the water. A pebble has more mass in it and more compact compared to a twig. The water cannot easily penetrate the pores of the pebble unlike twigs. That is why pebbles have greater densities than twigs.

Matter is anything that is made up of atoms. The matter word is mainly used in science. Therefore Option C are correct option.
Matter is a substance that has some mass and can occupy some volume. . Matter can be solid, liquid or gas.
In case of solid, particles are fixed at its mean position, they do not move at all. In gas, particles move very fast. They do not remain at its mean position. They continuously keep on moving with high kineticenergy called Brownian motion. In liquid particles are moveable, they are neither very stiff nor they move very fast. There is surface tension between the particles and the layers of liquid. Therefore, the layers of liquid just slide around each other. And this property of liquid is the reason for its fluidity.
Thus option c is correct option
