Human growth stages — choose a meaningful chronological order Items: a. Adult b. Child c. Infant d. Boy e. Adolescent

Introduction / Context:
Age-stage sequencing needs a biologically plausible order from earliest to maturity, passing through childhood and adolescence.

Given Data / Assumptions:

• Infant → Child → Boy (pre-teen/early teen male) → Adolescent → Adult.

Concept / Approach:
Arrange by age progression while recognizing gendered placeholder (Boy) precedes the broader adolescent category in this simplified model.

Step-by-Step Solution:
c (Infant) → b (Child) → d (Boy) → e (Adolescent) → a (Adult).

Verification / Alternative check:
Any order placing Adult earlier or skipping adolescent development is inconsistent.

Why Other Options Are Wrong:

• They start with Adult or reorder middle stages illogically.

Common Pitfalls:
Confusing adolescent with child; adolescent follows puberty onset.

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