Arrange the animals by approximate increasing body size/scale from the smallest organism to the largest. Items: (a) Elephant (b) Cat (c) Mosquito (d) Tiger (e) Whale

Introduction / Context:
Reasoning questions often ask you to rank entities by a single intuitive attribute. Here, that attribute is typical body size. We must sort five animals from smallest to largest based on well-known, everyday knowledge.

Given Data / Assumptions:

• (c) Mosquito: tiny insect, by far the smallest of the set.
• (b) Cat: small mammal, smaller than tiger and elephant.
• (d) Tiger: large wild cat, substantially bigger than a domestic cat but smaller than an elephant.
• (a) Elephant: one of the largest land animals, larger than a tiger.
• (e) Whale: largest on the list; many species exceed elephants by a wide margin.

Concept / Approach:
Use typical adult sizes under normal conditions. Extreme outliers and newborns are ignored in such questions. The monotonic order should increase continuously without any reversal.

Step-by-Step Solution:

Verification / Alternative check:
Any attempt to place cat after tiger or elephant contradicts common knowledge; placing whale anywhere but last also contradicts well-established size comparisons.

Why Other Options Are Wrong:

• Options that do not start with mosquito or do not end with whale violate the obvious extremes.
• Orders that put cat after tiger or elephant break the natural size gradient.

Common Pitfalls:
Confusing “largest land animal” (elephant) with “largest animal” overall (many whales). The question is about absolute size, not habitat-specific records.

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