Can we increase the size of statically allocated array?
Answer: B
Correct answer: No
A statically allocated array has its size fixed at compile time, in the stack frame or the data segment, and there is no mechanism to change it while the program runs.
The only way to get a larger array is to allocate a new one dynamically and copy the contents across - which is precisely what realloc does for heap blocks. This inflexibility is the central reason dynamic allocation exists, and it is why growable structures are always built on the heap.
