Arrange the Army ranks in a logical chain of command (from highest authority to lower): Items: a. Major b. Captain c. Colonel d. Brigadier e. Lt. General Choose the sequence from the most senior to the most junior.

Introduction / Context:
Rank ordering questions test general awareness of hierarchical structures. Here the list contains five commissioned ranks; we are to place them in descending seniority (highest to lowest).

Given Data / Assumptions:

• Ranks: Lt. General (e), Brigadier (d), Colonel (c), Major (a), Captain (b).
• We assume a standard hierarchy of seniority used in many armies.

Concept / Approach:
Recall the broad structure: General officers > field officers > company-grade officers. Lt. General is a three-star general officer above Brigadier (one-star), which in turn is above Colonel (senior field officer). Within company/field grades listed, Major outranks Captain.

Step-by-Step Solution:

Verification / Alternative check:
Cross-compare any two adjacent pairs: e>d>c>a>b is consistent with widely known command precedence.

Why Other Options Are Wrong:

• e,a,d,b,c and others: Mix ranks across categories, e.g., placing Major above Colonel/Brigadier is incorrect.
• None of these: Not needed since a standard chain exists.

Common Pitfalls:
Confusing Brigadier vs Colonel order; remembering “Brigadier” is a general officer grade above Colonel resolves this.

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