What is the output of the following program, where the zu format specifier in the printf statement below displays the result of sizeof as a decimal integer?

#include  #include  typedef union { double d; char c[20]; }U; int main() { U temp; temp.d = 11.5; strcpy(temp.c, "CS 354"); printf("%zu, %f, %s ",sizeof(temp), temp.d, temp.c); return 0; } 

20, Garbage value, CS 354

20, 11.5, CS 354

28, 11.5, CS 354

28, Garbage value, CS 354
