AIII, I, II, IV
-
BII, I, III, IV

CIII, IV, II, I
-
DIII, II, I, IV
Answer
Correct Answer: III, II, I, IV
Explanation
Introduction / Context:These terms combine a broad concept (nutrition) with specific physiological steps (digestion, absorption, excretion).
Given Data / Assumptions:Nutrition is the umbrella process of obtaining/processing food; digestion breaks food into absorbable units; absorption moves nutrients into the bloodstream; excretion removes waste.
Concept / Approach:Start with the overarching process label, then proceed with the bodily steps in order of occurrence after eating.
Step-by-Step Solution:
Nutrition (III) → Digestion (II) → Absorption (I) → Excretion (IV)Verification / Alternative check:This keeps absorption after digestion and places excretion last, which aligns with standard biology.
Why Other Options Are Wrong:They place absorption before digestion or excretion before core processing.
Common Pitfalls:Treating nutrition as one sub-step rather than the overall process.
Final Answer:III, II, I, IV
