Answer 2

b. Specialization is the process being used  here.

• The technical meaning of specialization is to divide an entity into sub entities.
• Here the base entity is 'vehicles' which further divided into two sub- entities - (i) 2 wheeler (ii) 4 wheeler.
• Further these two sub-categories are divided into more entities.
• Which suits the exact definition of Specialization.
