• Ans is Annie did it
  
  A fo annie , F fo fanny , D fo danny
  
  If A is true then other two false it creates contradiction
  If F is true then other two ate lieing then also contradiction between D n F
  Last when D is true then other are lieing but this does not create contradiction
  
  So when D is true then A has broken
  Note contradiction means if 1 statement correct himself then other become wrong automatically n vice versa
