Choose the meaningful micro→macro order: (A) substance (B) atom (C) molecule (D) proton

Introduction / Context:Chemical matter can be ordered from subatomic particles to bulk substance.

Given Data / Assumptions:Proton is subatomic; atoms consist of subatomic particles; molecules are bonded atoms; substances are macroscopic forms of matter.

Concept / Approach:Place the smallest building blocks first and the composite entities later.

Step-by-Step Solution:

Verification / Alternative check:This mirrors the hierarchy in chemistry.

Why Other Options Are Wrong:They put macro before micro or misorder atoms/molecules.

Common Pitfalls:Confusing “substance” with “molecule”—substance is bulk matter.

Final Answer:(D), (B), (C), (A)
