Suppose you wrote a program like HW9's rpn.c, except it was to read the input from a file opened with fopen instead of from stdin. Assume that code contains the line fscanf(f, "%s", buffer), where f was that opened file.  Based on this information, your code: A. Has a buffer overrun vulnerability B. Has a use-after-free vulnerability C. Has an uninitialized memory vulnerability D. Will cause a segmentation fault
