Answer
Correct Answer: d, a, c, b
Explanation
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
