Statement: There is an unprecedented rise in berth requests for long-distance trains during the current holiday season.\nCourses of Action:\nI. Immediately attach additional coaches to these trains to increase capacity.\nII. Advise people to plan travel after the holiday season.

Introduction / Context:
Seasonal demand spikes are predictable. The railways can expand capacity tactically; advising passengers to defer travel is not a service-oriented solution.

Given Data / Assumptions:

• Holiday peak demand now, not later.
• Railways can add coaches subject to rake length/platform constraints.
• Passenger plans are often date-bound.

Concept / Approach:
I improves availability immediately via additional coaches or special trains. II ignores service expectations and is impractical.

Step-by-Step Solution:
1) Deploy extra coaches/specials on high-demand corridors; dynamic waitlist management.2) Coordinate platform and rake schedules to handle longer formations.3) Communicate added capacity via app/website.

Verification / Alternative check:
Capacity addition aligns with public utility mandate; deferring travel is not relief.

Why Other Options Are Wrong:
Only II/Either/Both: II is not a remedy.

Common Pitfalls:
Ignoring safety limits on rake length; inadequate onboard services for added coaches.

Final Answer:
Only I follows.
