- 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
