Identify the correct decreasing order of bond dissociation enthalpy from the following.

In the manufacture of bromine from sea water,the mother liquor containing bromides is treated with:

Given below are two statements: Statement $(I)$: Oxidising power of halogens decreases in the order $F_2 > Cl_2 > Br_2 > I_2$, which is the basis of "Layer test". Statement $(II)$: "Layer test" to identify $Br_2$ and $I_2$ in aqueous solution involves the oxidation of bromide or iodide into $Br_2$ or $I_2$ respectively with $Cl_2$, which is a type of displacement redox reaction. In the light of the above statements, choose the correct answer from the options given below:

The number of interhalogens from the following having square pyramidal structure is.
$ClF_{3}, IF_{7}, BrF_{5}, BrF_{3}, I_{2}Cl_{6}, IF_{5}, ClF, ClF_{5}$
