Show answer & explanation
Correct answer: C
A stack is a linear data structure that follows the LIFO (Last In First Out) principle. Applications of stack include: Parenthesis balancing, where opening and closing brackets are matched.
Expression conversion, such as converting infix expressions to postfix form.
Process scheduling in an operating system uses a queue, not a stack. Hence, the correct answer is (A) and (C).
