Arrange the following stages of human growth in a meaningful developmental sequence: 1. Adult 2. Child 3. Infant 4. Boy 5. Adolescent. Which option correctly represents the order from the earliest stage to the latest?

Introduction / Context:
This question tests understanding of normal human developmental stages. We are given five labels describing stages of life and are asked to place them in chronological order, starting from the earliest stage after birth and ending with adulthood. Such questions rely on basic general knowledge rather than complex calculations.

Given Data / Assumptions:

• 1. Adult, 2. Child, 3. Infant, 4. Boy, 5. Adolescent.
• We assume a typical progression: infant to child to adolescent to adult.
• Boy in this context represents a male child, usually after the initial infant period.
• The sequence must reflect increasing age and maturity.

Concept / Approach:
Human development begins with infancy, then moves into childhood with early school years, then progresses into adolescence with puberty and teenage years, and finally into adulthood. The term boy here naturally falls between child and adolescent as a specific label for a growing male child beyond infancy. Adult is always the last stage among the given options.

Step-by-Step Solution:
Step 1: The earliest stage is Infant (3). This is the phase shortly after birth.Step 2: After infancy, the next broader stage is Child (2), which covers early childhood.Step 3: Boy (4) represents a growing male child, generally older than a small child but not yet an adolescent. Therefore it comes after the generic child stage.Step 4: Next is Adolescent (5), which represents the teenage years and the period of puberty.Step 5: Finally, the fully grown stage is Adult (1).Step 6: Putting this all together, the correct chronological order is 3, 2, 4, 5, 1.

Verification / Alternative check:
Read the sequence as words: Infant, Child, Boy, Adolescent, Adult. It clearly reflects natural progression from babyhood to early childhood, then to a somewhat older boy, then to adolescence, and finally adulthood. Any other arrangement that places Adult earlier or Infant later would violate common sense.

Why Other Options Are Wrong:
Option A starts with Adult, which is clearly not the earliest stage. Option B begins with Child and then Infant, which reverses the correct order. Option C places Adult before Adolescent, which is again out of order. Thus, none of these alternatives represent the full life sequence correctly.

Common Pitfalls:
Sometimes candidates confuse the labels Child and Boy, but in such questions the intention is to treat Infant as the earliest stage, Adult as the latest, and arrange the others based on intuition about age. Overthinking the exact definitions of each term is unnecessary; basic life progression is sufficient to answer correctly.

Final Answer:
The correct developmental sequence from earliest to latest is 3, 2, 4, 5, 1, corresponding to Infant, Child, Boy, Adolescent, and Adult.
