Explanation:
Atom is the smallest unit of matter which was earlier thought to be indestructible but later new findings suggested that atom contains sub-atomic particles.
The arrangements of these sub-atomic particles in an atom were represented by many models, best accepted of which is presented by Ernest Rutherford in 1911.
His experimental findings concluded that a dense heavy nucleus is present in the center of an atom which is surrounded by a negatively charged nucleus.
Thus, the selected option is the correct answer.
