Answer:
Option 2 i.e., instance methods is the correct answer to the following question.
Step-by-step explanation:
Because the instance method or function is the function that needed the class object to be called.
For Example:
//header file 
#include <iostream> 
using namespace std; 
//define class 
class Test 
{ 
public: 
//instance method 
void getins() 
{ 
cout<<"I AM Instance method"; 
} 
}; 
int main() 
{ 
//creating object 
Test obj; 
//calling of instance method through class object 
obj.getins(); 
}
Output:
I AM Instance method
