Which of the following transitions in a hydrogen atom emits a photon of the highest frequency?

Which of the following is incorrect for garden pea?

If $A$ is a non-zero square matrix of order $n$ with $\operatorname{det}(I+A) \neq 0$ and $A^3=O$,where $I$ and $O$ are the unit and null matrices of order $n \times n$ respectively,then $(I+A)^{-1}$ is equal to
