Which of the following is incorrect order of property indicated?

As the atomic scale grows, the bond dissociation energy often reduces while advancing down a group. F₂ has a lower bond dissociation energy than Cl₂ and Br₂, nevertheless. This is caused by fluorine's tiny atomic size. As a result, the following is the ascending order of bond dissociation energy among halogens.

So, the option is correct ${\mathrm{F}}_2>{\mathrm{Cl}}_2>{\mathrm{Br}}_2>{\mathrm{I}}_2$.

Hence correct option is A.
