If you are using a serverside listbox then change the following property

change it from...
Object.mulitple=true

to

Object.mulitple=false

but dont forget to check that B selected first.

dim Test as boolean = False
dim Marker as integer

for i = 0 to Object.items.count - 1
  If object.items(i).selected then
    if object.items(i).text = "B" Then
      Test = true
      Marker = i
      Exit For
    end if
  end if
next
If Test Then
  For i = 0 to Object.items.count - 1
    Object.Items(i).selected = False
  Next
  Object.Multiple = False
  Object.items(Marker).selected = true
End If
