Pre-operational stage in Jean Piaget’s theory of cognitive development characterizes _________.

The correct answer is Centration in thought.

Jean Piaget's theory of cognitive development proposes four distinct stages of intellectual development. Among these, the Pre-operational stage (which typically occurs from ages 2 to 7 years) is characterized by several key features and cognitive limitations:
1. Centration: This is the tendency to focus on only one salient aspect of a situation or object while neglecting other relevant features. For example, if water is poured from a wide glass into a tall, thin glass, a child in this stage will focus only on the height of the water level and conclude there is more water, ignoring the width.
2. Egocentrism: The inability to see a situation or view from another person's perspective.
3. Irreversibility: The inability to mentally reverse a sequence of events or operations.

Let's analyze the other options to understand why they belong to different stages:
- Development of abstract thinking and Hypothetico-deductive thinking are key milestones of the Formal operational stage (ages 11 years and above), where adolescents begin to think systematically about abstract concepts and test hypotheses.
- The Ability to conserve and seriate objects is acquired during the Concrete operational stage (ages 7 to 11 years), where children overcome centration and develop logical thinking about concrete, physical objects and relations.

Therefore, the pre-operational stage is uniquely characterized by Centration in thought.
