Step 1: Understanding the Question.
We are given four possible interventions Mr. Thakur could have taken, and asked to rank them from the one with the biggest positive impact on the organisation to the one with the smallest, then match that order to an option.
Step 2: Key Formula or Approach.
Judge each intervention by how directly and how permanently it fixes the actual root problem, which is that night shift supervisors had no channel to discuss their wage contracts before those contracts were imposed. An intervention that is not grounded in a caselet fact, or that only delays the problem, ranks lower than one that structurally solves it.
Step 3: Detailed Explanation.
Statement 2, creating a process for night shift supervisors to interact with Mr. Thakur, goes straight at the actual gap described in the caselet: night shift supervisors, unlike day shift ones, never got one-on-one negotiation. Fixing this gap has the highest organisational impact because it solves the real problem for the whole night shift group, not just Ram Lal.
Statement 3, an open door policy for all employees, has real but slightly lower impact, since it helps every employee reach Mr. Thakur, but it is a broader, less targeted fix than a process built specifically for the group that was actually left out.
Statement 1, delegating wage negotiation to the Personnel Department, is a workable option but it changes who does the negotiating rather than guaranteeing that negotiation happens at all; it ranks below the two above.
Statement 4 rests on a detail, supervisors being rotated across shifts every two months, that is never mentioned anywhere in the caselet. An intervention built on an assumption not supported by the passage cannot be relied on, and postponing a decision does not solve the underlying access problem anyway, it only delays it. So statement 4 has the least organisational impact among the four, not the most.
Putting these together, the order from highest to lowest impact is 2, 3, 1, 4, which is option E in the original five-option list.
Step 4: Final Answer.
The ranking of decreasing organisational impact is: create a night shift interaction process, then an open door policy, then delegation to Personnel, then the two-month postponement.
