Classification is a fundamental skill in verbal reasoning that involves grouping words or objects based on shared characteristics. In competitive exams, this skill helps you quickly identify the item that does not belong to a group - often called the "odd one out." By recognizing common properties, you can eliminate options and arrive at the correct answer efficiently.
For example, consider the group: Apple, Banana, Carrot, Mango. At first glance, three are fruits and one is a vegetable. Identifying the vegetable as the odd one out is the essence of classification.
