Life stages — order these human growth phases from earliest to mature: a) Foetus b) Child c) Baby d) Adult e) Youth

Introduction / Context:
Arrange prenatal to adult stages logically.

Given Data / Assumptions:

• Foetus → Baby → Child → Youth → Adult.

Concept / Approach:
Use biological progression: prenatal, neonatal, childhood, adolescence/young adult, adulthood.

Step-by-Step Solution:
Foetus (a) precedes birth.Baby (c) comes after birth.Child (b) follows infancy.Youth (e) bridges to maturity.Adult (d) is final.

Verification / Alternative check:
Standard growth charts support this order.

Why Other Options Are Wrong:
They invert prenatal/postnatal order or place adult too early.

Common Pitfalls:
Equating “youth” with “child”; here it means young adult/late teen.

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