Question

Which of the following statements is correct?

• A. Every class containing abstract method must not be declared abstract
• B. Abstract class cannot be directly initiated with new operator
• C. Abstract class cannot be initiated
• D. Abstract class contains definition of implementations

Answer 1

C is true and hence the ans Abstract classes may not be instantiated

Option A false because 

A method that is declared as abstract and does not have implementation is known as abstract method.

Abstract classes are classes that contain one or more abstract methods.

Option D is false because :-

Anabstract method is a method that is declared, but contains no implementation.

Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.

Option B is not false either but A seems to be more appropriate

Comments

option B & C both are correct.

Abstract Class can directly  initiated with "new " operator.

Abstract class  can be initiated.

Answer 2

answer :b

abstract class cannot create objects

therefore they cannot be accessed directly using the new operator

Answer 3

Ans: B and C both are correct.

1. Abstract class cannot be directly initiated with new operator
2. Abstract class cannot be initiated
