Correct answer: B
Answer: The constructors called for each line are explained below.
Student S1; — Default constructor is called because a new object is created without using any existing object.
Student S2 = S1; — Copy constructor is called because a new object (S2) is initialized using an existing object (S1).
Therefore, the correct result is: default constructor for the first line and copy constructor for the second line.
