Question

(b) Fill half the beaker with water and mark the level of water.

(c) Dissolve some salt / sugar with the help of a glass rod.

(d) Observe any change in water level.

dissolve salt in water, the particles of salt get into the spaces between particles of water. This shows the particulate nature of matter.
