Which of the following are in the same row ?
Answer: A
The given information can be analysed as follows :
E is not at end. So, E must be in the middle of one of two rows.
D is second to the left of F. So, order of the row must be D -- F.
C is neighbour of E and is sitting diagonally opposite to D means C is under F in the other row
i.e. D __ F
__ E C
B is the neighbour of F.
So, the arrangement must be D B F & A E C
Clearly, from amongst the given alternatives, A and E are in the same row. So, the answer is (a).
