Abstract base class may be used only as framework from which other class will be derived, while the individual objects of this class will never be instantiated.

Talking in terms of java, an abstract class can have any number of instances but can't have any object. But since this question. Is listed in oops concept, option d is correct.

Memory Allocation to the class members is done when its object is created. For an abstract class, memory cannot be allocated as its resource requirement cannot be calculated. Hence no object for an abstract class.

Abstract class is not a main class to automatically create a object, only create reference to that particular class itself.

According to me. We cannot create the object of the abstract class but we can create many time instances of the abstract class.

We can not create object of an abstract class because abstract class is incomplete class.
