Six persons A, B, C, D, E and H are sitting in a straight row facing north. From the left to the right, they are arranged in the fixed order H, B, C, D, A and E. Based on this arrangement, which one of the following statements is definitely true?

Introduction / Context:
In this reasoning question, you are given a fully specified linear arrangement of six persons and are asked which statement among the options is definitely true. Because the order is fixed and there is no ambiguity, we can directly check each statement against the arrangement to see whether it holds or fails.

Given Data / Assumptions:

• Persons: A, B, C, D, E and H.
• They sit in a single row facing north.
• From left to right, the seating order is: H, B, C, D, A and E.
• “Immediate right” or “immediate left” refers to the next seat directly adjacent in that direction.

Concept / Approach:
We will:

• Write down each position from left to right.
• Interpret each statement exactly and check it against the arrangement.
• Identify which statement is consistent with the given order and true in every possible interpretation (here there is only one arrangement).

Step-by-Step Solution:
Step 1: Label positions from left to right: Position 1: H, Position 2: B, Position 3: C, Position 4: D, Position 5: A, Position 6: E. Step 2: Check option (a): “D is second to the left of H”. To be second to the left of H, D would need to appear two seats before H. But H is already at the extreme left (position 1), so D cannot be two seats to the left. So option (a) is false. Step 3: Check option (b): “A is second to the right of E”. E is at position 6, the far right. No one sits to the right of E, so A cannot be second to the right. Option (b) is false. Step 4: Check option (c): “C is to the immediate right of B”. B is at position 2, and C is at position 3. Since position 3 is directly to the right of position 2, C is indeed immediately to the right of B. Option (c) is true. Step 5: Check option (d): “E is to the immediate left of C”. E sits at position 6 and C at position 3, so they are far apart; E is not immediately left of C. Option (d) is false. Step 6: Check option (e): “B is to the immediate left of H”. Actually, H is at position 1 and B at position 2. So H is to the immediate left of B, not the other way around. Option (e) is also false.
Verification / Alternative check:
Whenever you have a fully known arrangement, it can help to draw a quick sketch or table. This ensures that you do not accidentally reverse left and right or misread the relative positions. Rechecking the sketch confirms that only statement (c) matches the arrangement exactly.

Why Other Options Are Wrong:
Option (a): Impossible because H is at the leftmost seat, so no one can be second to its left. Option (b): E is already at the rightmost seat; nothing can be to its right, let alone two seats away. Option (d): There are two people between C and E, so E is not immediately left of C. Option (e): The roles of H and B are reversed; H is left of B, not vice versa.
Common Pitfalls:
Examine takers sometimes misinterpret “left” and “right” because they forget that everyone is facing north, so the diagram they draw must match that orientation. Another pitfall is to rely on mental imaging without writing the positions, which increases the risk of errors, especially under time pressure.

Final Answer:
The statement that is definitely true is “C is to the immediate right of B”.
