0. Match the following with reference to object-oriented modeling.
| List I | List II |
| (a) Polymorphism | (i) Picking both operator and attributes with operations appropriate to model an object |
| (b) Inheritance | (ii) Hiding implementation details of methods from users of objects |
| (c) Encapsulation | (iii) Using similar operations to do similar things |
| (d) Abstraction | (iv) Create new classes from the existing class |
Codes:
| (a) | (b) | (c) | (d) | |
| (1) | (iv) | (iii) | (i) | (ii) |
| (2) | (iii) | (iv) | (i) | (ii) |
| (3) | (iii) | (i) | (ii) | (iv) |
| (4) | (iv) | (iii) | (ii) | (i) |
- Option : B
- Explanation :
- Using similar operations to do similar things is Polymorphism
- Create new classes from existing class is Inheritence.
- Picking both operator and attributes with operations appropriate to model an object is encapsulation
- Hiding implementation details of methods from users of objects is Abstraction
So, option (B) is correct.
