$A$ molecule with the formula $AX_4Y$ has all its elements from the $p-$block. Element $A$ is the rarest,monoatomic,non$-$radioactive element from its group and has the lowest ionization enthalpy value among $A, X,$ and $Y$. Elements $X$ and $Y$ have the first and second highest electronegativity values,respectively,among all known elements. The shape of the molecule is:
