A and B are the parents of C but C is not the daughter of A. What is C to A?

Appeared in: ESIC Nursing Officer 2016 (shift-1)

Explanation

The first statement, 'A and B are the parents of C,' establishes that C is the child of A.
The second statement, 'C is not the daughter of A,' eliminates the possibility of C being female.
Since a child can only be a son or a daughter, and C is not a daughter, C must be the son of A.

Option A: An uncle is the brother of one's parent. C is the child of A, not A's brother.
Option C: A grandson is the son of one's child. C is the direct child of A, not the child of A's child.
Option D: A brother is a male sibling. C is the child of A, not A's sibling.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning (Blood Relations) as background academic context rather than a clinical decision trigger.
Logical reasoning is a critical skill for nurses to interpret patient information, connect symptoms, and make sound clinical judgments.
This type of problem-solving helps in understanding complex family histories and genetic relationships when taking a patient's medical history.
What if the question was 'What is B to C?' If B is the mother, the answer is 'Mother'. If B is the father, the answer is 'Father'. The information given doesn't specify the gender of A or B, only that they are parents.

How to Approach the Question

First, identify the core relationships given: 'A and B are parents of C'.
Next, note the specific condition or negation: 'C is not the daughter of A'.
Translate the relationships into a simple structure. 'Parents of C' means C is their child.
Apply the negation. If a child is not a daughter, the only other possibility is a son.
Evaluate each option against your deduced relationship ('Son') to find the correct match.
