Arrange the stages of human growth and development from earliest (prenatal) to latest (adulthood): a) Fetus (prenatal) b) Child c) Baby (infant) d) Adult e) Youth (adolescent) Select the most appropriate chronological sequence.

Introduction / Context:
This item assesses understanding of the natural order of human development. Terms include prenatal and postnatal stages, as well as social labels for maturing individuals. We must map them to a universally accepted chronological path.

Given Data / Assumptions:

• a) Fetus occurs before birth (prenatal stage).
• c) Baby denotes an infant shortly after birth.
• b) Child follows infancy.
• e) Youth represents adolescence (teen years).
• d) Adult follows youth.

Concept / Approach:
Sort by strict biological and social chronology from prenatal to adulthood. No overlaps are allowed to break the order (e.g., a child cannot precede a baby).

Step-by-Step Solution:
Start with a) Fetus.Then c) Baby, the immediate postnatal stage.Next b) Child.Then e) Youth (adolescent).Finally d) Adult.Thus: a, c, b, e, d.

Verification / Alternative check:
Any order placing adult or youth before baby/child contradicts development chronology.

Why Other Options Are Wrong:

• e, d, b, c, a: starts from youth/adult; reversed.
• a, b, d, c, e: adult inserted before baby/youth.
• b, c, e, d, a: ends with fetus; impossible.
• None of these: not applicable; a correct order exists.

Common Pitfalls:
Equating “baby” with “child”; in reasoning tests, baby (infant) precedes child.

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