Animal sizes — arrange these organisms in increasing size order (smallest to largest): (a) Elephant (b) Cat (c) Mosquito (d) Tiger (e) Whale

Introduction / Context:
Everyday knowledge helps in arranging organisms by relative size. We go from an insect to domestic/wild mammals and finally the largest animal.

Given Data / Assumptions:

• Organisms: Mosquito, Cat, Tiger, Elephant, Whale.
• We compare typical adult sizes; subspecies variations do not affect rank ordering.

Concept / Approach:
Use clear magnitude differences: insects < small mammals < large wild cats < megafauna < marine giants.

Step-by-Step Solution:
1) Mosquito (c) — tiny insect.2) Cat (b) — small mammal, clearly larger than an insect.3) Tiger (d) — big cat, heavier than domestic cats.4) Elephant (a) — huge terrestrial mammal.5) Whale (e) — includes blue whale, largest known animal.

Verification / Alternative check:
Average body mass/length data confirm the ascending order chosen.

Why Other Options Are Wrong:

• Any that place whale early or mosquito late are inconsistent with obvious size gaps.
• Orders swapping cat and tiger violate common knowledge of big cats.

Common Pitfalls:
Overthinking subspecies or juveniles; the test expects typical adult sizes.

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