Arrange the developmental stages from earliest to latest: a) Neonate (newborn, first 28 days) b) Child c) Infant (up to 1 year, broader than neonate) d) Embryo (prenatal) Select the correct chronological sequence.

Introduction / Context:
The task is to order human developmental labels by time. Some terms overlap (neonate ⊂ infant), so we must respect the narrower window inside the broader category while keeping the global chronology consistent.

Given Data / Assumptions:

• d) Embryo: prenatal stage prior to birth.
• a) Neonate: 0–28 days after birth.
• c) Infant: up to 1 year; includes the neonatal period.
• b) Child: follows infancy.

Concept / Approach:
Place the strictly prenatal stage first, then immediate postnatal (neonate), then the broader infancy period, then childhood.

Step-by-Step Solution:
1) d) Embryo.2) a) Neonate.3) c) Infant.4) b) Child.Sequence: d, a, c, b.

Verification / Alternative check:
Ensure no stage includes a later stage: neonate is a subset of infant, so neonate must come before “infant” as a label in a strict sequence.

Why Other Options Are Wrong:
Any answer placing embryo after birth or child before infant violates chronology.

Common Pitfalls:
Treating “infant” and “neonate” as synonyms; neonate is a narrower early subset.

Final Answer:
d, a, c, b
