Understanding the Coach Arrangement
To solve the problem, we must analyze the arrangement of the coaches based on the given conditions:
  • There are 7 coaches: AC-I, AC-II, AC-III, I, II, GC, and LC.
  • AC coaches (AC-I, AC-II, AC-III) and non-AC coaches (I, II, GC, LC) cannot be adjacent.
  • GC is at the front of AC-II, and LC is at the back of AC-II, with LC not at an extreme end.
  • Compartment I is the only one between AC-I and AC-III.


Possible Arrangement
Given that GC must be at the front of AC-II and LC at the back:
1. Position of GC and LC:
- GC is at the first position (1st) and LC can only be at the last position (7th) because it cannot be at an extreme end.
2. Structure of Coaches:
- The arrangement must alternate between AC and non-AC coaches. Thus, we can derive a possible arrangement:
1. GC
2. AC-II
3. I
4. AC-I
5. II
6. AC-III
7. LC

Evaluating the Statements
  • a) Either AC-I or AC-III is at an extreme end.
    Can be true as AC-I or AC-III can be at the end in other arrangements.
  • b) Either AC-I or AC-III is the second coach from the engine.
    This cannot be true since AC-II is positioned second, leaving no room for AC-I or AC-III to be second.
  • c) AC-III is the fourth coach from the engine.
    Can be true as per the arrangement where AC-III is the sixth coach.
  • d) AC-I is the fifth coach from the engine.
    Can also be true since AC-I can occupy the fourth position in a different arrangement.


Conclusion
The statement that cannot be true is option b) as it contradicts the fixed position of AC-II.
