I got this question in examination.

My enquiry is from Buffer Memory in division Buffering and other Data Structures of Embedded Systems

Answer 1

The correct answer is (c) malloc() and unmalloc()

To explain I would say: The malloc() and the unmalloc() are the system calls which is used by the UNIX operating system which allocates the memory dynamically and returns it.
