Solution

a and b

Explanation:

Bohr proposed a model for the hydrogen atom which is also applicable for some lighter atoms in which a single electron revolves around a stationary nucleus of positive charge Ze (called a hydrogen-like atom, e.g.: H, He+, Li+2, Na+1 etc). It is not applicable to hydrogen in the molecular form and also, it will not be applicable as it is for a He-atom.
