The SRP for the different halogens is in the order of;

 The SRP for the different halogens is in the order of $\mathrm{F}>\mathrm{Cl}>\mathrm{Br}>\mathrm{I}$. Detailed explanation: SRP stands for standard reduction potential value. The higher the SRP value, the stronger the oxidizing agent due to high electron affinity, low bond energy, and small size.

Hence, the correct answer is option A) $\mathrm{F}>\mathrm{Cl}>\mathrm{Br}>$ I
