In this verbal reasoning question on family relationships, select the one word that is odd or different from the other given alternatives.

Introduction / Context:

This question belongs to the category of verbal reasoning and tests your understanding of basic family relationships. You are given a list of close relatives and asked to select the odd one out. To answer correctly, you must identify the common property that most of the words share and then find the single option that does not follow that property. Such questions are very common in government and bank exams because they quickly check conceptual clarity and observation skills.

Given Data / Assumptions:

- Sister is a female sibling.
- Daughter is a female child.
- Aunt is a female relative (father's or mother's sister, or uncle's wife).
- Mother is a female parent.
- Nephew is the son of one's brother or sister and is male.
- The task is to select the odd word from these alternatives.

Concept / Approach:

The standard approach in odd one out questions is to first group the given words based on gender, type of relation, or generation. Here, all the options are family relationships, so the deciding factor will not be whether they are relatives but what specific type of relatives they are. The most natural property to check is gender, because four of the words generally describe female relatives, while one word describes a male relative. The option that does not match the predominant gender category becomes the odd one.

Step-by-Step Solution:

Verification / Alternative check:

An alternative way to verify the answer is to check whether the relationship is direct or indirect. Sister, daughter and mother are direct relations, while aunt is a slightly extended relation. However, both aunt and nephew are extended relations, so that criterion does not uniquely isolate any one term. The gender-based classification clearly isolates only nephew as male, while the remaining four words point to female family members. This confirms that our chosen answer is consistent and logically sound.

Why Other Options Are Wrong:

Sister is a female sibling and matches the majority female category, so it cannot be the odd one out.

Daughter is a female child and again belongs to the female group of relations, so it matches the pattern.

Aunt is a female relative and therefore still falls in the predominant female category.

Mother is also a female relation and does not stand out as different when compared with sister, daughter and aunt.

Common Pitfalls:

Candidates sometimes overcomplicate this type of question by looking for subtle distinctions such as generational level or whether the relation comes from the mother's or father's side. While such distinctions can sometimes be relevant, here the simplest and most robust criterion is gender. Another common mistake is not checking all options carefully and quickly guessing one that feels slightly less familiar. Always verify that exactly one option is different on a clear, objective property.

Final Answer:

The only male relation among the options is Nephew, so it is the odd word out.
