Assertion(A): call by value is known as pure method
Reason(R): The original value of variable does not change as operation is
performed on copied values.
(a) Both Assertion (A) and Reason (R) are true and Reason (R) is a correct
explanation of Assertion (A)
(b) Both Assertion (A) and Reason (R) are true and Reason (R) is not a
correct explanation of Assertion (A)
(c) Assertion (A) is false and Reason (R) is true
(d) Assertion (A) is false and Reason (R) is true
Solution
(a) Both Assertion (A) and Reason (R) are true and Reason (R) is a correct
explanation of Assertion (A)
