Human development micro-stages (earliest to latest): Arrange— (a) Infancy, (b) Childhood, (c) Adulthood, (d) Babyhood, (e) Adolescence.

Introduction / Context:
Some syllabi distinguish babyhood and infancy as very early stages. After these come childhood, adolescence, and adulthood.

Given Data / Assumptions:

• Babyhood and infancy are both pre-childhood; several boards place “babyhood” (newborn/toddler) before a broader “infancy”.
• Adolescence is the transition to adulthood.

Concept / Approach:
Sequence early micro-stages before broader childhood, then adolescence, then adulthood.

Step-by-Step Solution:

Verification / Alternative check:
Among provided sequences, this preserves early stages first and adult last.

Why Other Options Are Wrong:
They place adulthood before adolescence/childhood or scatter the early micro-stages.

Common Pitfalls:
Treating babyhood and infancy as identical and ignoring option constraints.

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