Answer 2

The correct option is 'd' as the movement of electrons in discrete energy levels prevent an atom from being collapsed.

Detailed Explanation

• The centrifugal force prevents collapsing of atoms due to movement of electrons.
• When the electrons stop moving, the attractive force inside the nucleus attract the electrons towards it thus resulting in collapse of the atoms.
• Due to movement of electrons, there is balance of potential and kinetic energy that also prevents collapsing of atoms.
