Only iodine forms hepta -fluoride `IF_(7)`, but chlorine and bromine give penta -fluorides.The reason for this is

A

low electron affinity of iodine

B

unsual pentagenal bipyramidal structure of `IF_(7)`

C

that the larger iodine atom can accommodate more number of smaller fluorine atom around it

D

low chemical reactivity of `IF_(7)`
