Six students - A, B, C, D, E, and F.

1) A is at one corner and F is beside him.

According to the above information, there are two cases:

                            Case (1)                                                              Case (2)  

  • As given A is at one corner it could be left or right. F is beside A in both cases.

2) B is at the second place from the right end.

Here case (1) gets eliminated.

  • As B is the second place from the right then A has to be in the left corner because F is always beside A and if A is at the right end then F has to be in the second place from the right end.

3) B is to the immediate right of E.

  • As given C is not beside F means there is the only place where C stands is the right end after that only place remaining for D is between E and F.
  • So, according to the above diagram "C standing at the right end".

Hence, the correct answer "Option 4"  .
