Choose the correct sequential order of rainbow colours among the given subset: Given list: a. Red b. Green c. Violet d. Yellow e. Orange Arrange them as they appear in the natural rainbow order from top (outer) to bottom (inner), limited to these five colours.

Introduction / Context:The natural rainbow order (from outer to inner) is V I B G Y O R. The options provide only a subset of these colours; we must preserve the correct relative order among the ones listed.

Given Data / Assumptions:

• Available: Violet (c), Green (b), Yellow (d), Orange (e), Red (a).
• Missing: Indigo and Blue, which we ignore while maintaining correct sequence.

Concept / Approach:Write the canonical sequence V I B G Y O R, then drop absent colours, keeping the remaining in the original order.

Step-by-Step Solution:

Verification / Alternative check:Any order that places red before orange or green before violet contradicts the standard spectrum ordering.

Why Other Options Are Wrong:

• d,c,b,e,a or c,d,b,a,e: Disrupt the V–G–Y–O–R order.
• b,e,d,a,c: Places green at the outer end and violet at the inner end—reversed relative positions.

Common Pitfalls:Confusing camera/printing palettes (RGB/CMYK) with spectral ordering; they are different concepts.

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