Explanation:

Let's analyze each statement about the arrangement:

- 6 students: A, B, C, D, E, F stand in a line facing north.

- "A is at one of the corners and F is beside him."

- "B is to the immediate right of E."

- "B is at the second place from the right end."

- "C is not beside F."

Let's build the line from the right since B is at 2nd from right.

Positions: 1 2 3 4 5 6 (from left to right)

- So, B is at position 5.

- Since B is immediately right of E, E is at position 4.

- Only possible corners for A are position 1 or 6. Try both, but note F must be beside A.

- Try A at position 1: F at position 2. Now, positions filled: 1(A), 2(F), 4(E), 5(B)

- C cannot be beside F so C cannot be at 3. So, C must be at 6, D at 3.

- Lineup: 1(A), 2(F), 3(D), 4(E), 5(B), 6(C)

Third from right: position 4, that's E.

Option 1: E

Summary of options:

- 1. E (Correct)

- 2. F (Position 2, not third from right)

- 3. C (Position 6, rightmost)

- 4. D (Position 3, third from left)

Correct answer is E, third from the right.
