Solution

The correct option is D The atom is composed of diffused ball of positive charge with negative particles dispersed throughout.
The atom is composed of diffuse ball of positive charge with negative particles dispersed throughout like a watermelon where the red part is the positive sphere and the seeds represent negatively charged particles.

Hence, the correct option is $D$ .
