Verification of truth — must-have relationship: A child must have had which of the following?

Introduction / Context:
This item asks for a condition that is necessarily true for the existence of a child, independent of culture, economics, or social circumstances.

Given Data / Assumptions:

• “Child” refers to a human offspring.
• We are considering biological necessity, not social opportunities or possessions.

Concept / Approach:
By biological reproduction, every child necessarily has parents (at minimum, a biological mother and father, or donor equivalents). Toys, friends, and formal education are culturally contingent and not guaranteed.

Step-by-Step Solution:

Verification / Alternative check:
Even in exceptional reproductive technologies, the concept of parentage (genetic/gestational) persists; friendships, toys, and schooling vary widely.

Why Other Options Are Wrong:

• Toys: Not necessary.
• Friends: Not guaranteed.
• Education: Access varies; not universal.
• None of these: Incorrect since “parents” is necessary.

Common Pitfalls:

• Confusing common childhood experiences with definitional necessities.

Final Answer:

parents
