To answer this question, you need to understand the concept of pointers in programming.
Option A) Vptr - This option is incorrect because "Vptr" is not a commonly used pointer type. It is not related to the concept of a pointer that takes a value as zero.
Option B) Void - This option is incorrect because "void" is not a pointer type. It is used as a return type for functions that do not return a value.
Option C) Null - This option is correct. "Null" is a special value that can be assigned to a pointer to indicate that it points to nothing. In many programming languages, including C and C++, a null pointer is represented by the value zero.
Option D) Zero - This option is incorrect because "Zero" is not a pointer type. It is simply a numerical value that represents the absence of a value.
The correct answer is C) Null. This option is correct because a null pointer is a type of pointer that generally takes a value of zero.
