Redox Reactions · Halogen displacement and layer test

Given below are two statements :

Statement (I) : Oxidising power of halogens decreases in the order $\ce{F2}$ $>$ $\ce{Cl2}$ $>$ $\ce{Br2}$ $>$ $\ce{I2}$ , which is the basis of “Layer test”.

Statement (II) : “Layer test” to identify $\ce{Br2}$ and $\ce{I2}$ in aqueous solution involves the oxidation of bromide or iodide into $\ce{Br2}$ or $\ce{I2}$ respectively with $\ce{Cl2}$ , which is a type of displacement redox reaction.

In the light of the above statements, choose the correct answer from the options given below :

(1)Both Statement I and Statement II are true
(2)Both Statement I and Statement II are false
(3)Statement I is true but Statement II is false
(4)Statement I is false but Statement II is true
