Ans:-B
 

Explanation:-

Generalisation and specialization are two terms that have a opposite meaning. In generalization the differences between members of an entity is minimized. Generalisation is a bottom up process. It goes from more specific to more general. For example, if the subclasses are taken as car and bike they would fall under the category of superclass called vehicle. From the subclasses we would identify features which can take us to the superclass vehicle.

Specialisation is the opposite of this. In Specialisation the differences between members of an entity are maximized. Specialisation is a top down process. It goes from more general to more specific. If vehicle is a super class and car and bike are its subclasses, identifying the characteristics or uniqueness of its subclasses is what happens in specialization

A generalization is a bottom-up approach in which two lower-level entities combine to form a higher-level entity. In generalization, the higher-level entity can also combine with other lower-level entities to make further higher-level entity.

Generalization helps in reducing the size of schema

Generalization club all the entities that share some common properties to form a new entity.

In generalization, a higher entity must have some lower entities

Generalization is always applied to the group of entities

Generalization results in a formation of a single entity

Option B is correct.
