Which of the following statement (s) is // are true?

If H-atoms are in 3rd energy level then number of maximum different spectral lines produced by 2 atoms will be equal to number of maximum spectral lines produced by 3 H-atoms.

For third excited state, `He^(+)` ions and maximum number of different spectral line produced by 4 H-atoms are equal.

Energy evolved from 3rd to 2nd energy level transition in `He^(+)` can be used ot ionise `Li^(2+)` from ground level.

Energy evolved by a `He^(+)` ion which is in its 1st excited state can ionise a hydrogen atom which is in its ground state.

a, c, and d are points of equilibrium

a is a point of stable equilibrium

b is a unstable equilibrium point

All of the above
