Arrange these Indian Army commissioned ranks in ascending order of seniority (lowest to highest): (a) Major (b) Captain (c) Colonel (d) Brigadier (e) Lieutenant General. Select the correct sequence based on standard rank structure.

Introduction / Context:
This item assesses knowledge of a common hierarchical order—in this case, commissioned ranks in the Indian Army. Even without memorizing every rank, you can reason from general awareness that “Captain” is junior to “Major,” which is junior to “Colonel,” and so on, up to “Lieutenant General.”

Given Data / Assumptions:

• Ranks provided (unordered): Captain, Major, Colonel, Brigadier, Lieutenant General.
• We must arrange them from lowest to highest seniority.

Concept / Approach:
Standard seniority (omitting ranks not listed here like Lieutenant Colonel and Major General) follows: Captain < Major < Colonel < Brigadier < Lieutenant General.

Step-by-Step Solution:
Identify the lowest among the given set: Captain (b).Next rung: Major (a).Then: Colonel (c).Then: Brigadier (d).Highest among the set: Lieutenant General (e).

Verification / Alternative check:
Cross-check memory of common rank lists or recall that star insignia and appointments increase through Colonel to Brigadier to the general officer grades (Lieutenant General higher than Brigadier).

Why Other Options Are Wrong:
Any ordering that places Major below Captain, or Brigadier below Colonel, or Lieutenant General anywhere but the top is inconsistent with the widely accepted hierarchy.

Common Pitfalls:
Confusing “Lieutenant” with “Lieutenant General” (the latter is a very senior general officer, far above Captain/Major).

Final Answer:
b, a, c, d, e
