In SBI PO mock prelims 22, inside 76th question, an instruction is given that A, D are not neighbours of F. But in solution A is neighbour of F. Is it possible?

The question tells that A and D are not neighbors..But there is no restrictions regarding the neighborhood of A and F as it is not mentioned. So, A and F can be neighbors..

I am sorry i read as A and D are not neighbors.. Yea you're right it is not possible for A to be the neighbor of F as it is restricted.. Try other way of arrangements..
