### Description

We discuss the correlation between the $B \to K^{(\ast)} \nu \nu$ and $B \to K^{(\ast)} \ell \ell$ decay modes in the Standard Model (SM) and its several popular extensions. This helps obtaining more accurate SM determination of $\mathcal{B}(B \to K^{(\ast)} \nu \nu)$ which is useful in view of the upcoming experimental measurement at Belle-II. In addition to that, we also show the impact of the measurements of $R(K^\pm)$ and $R(K^0)$ on the scenarios with extra sterile neutrinos.
