Your Answer for Question 1:
a) This is because malloc calls upon the operating system to obtain more memory as needed. malloc always asks for more memory so it will never leave the number of free blocks change and malloc doens't free memory so it may not increase the number of free blocks.

Your Answer for Question 2:
a. THis is true because free always frees blocks.

c is true because blocks can be combined into bigger blocks if they are next to each other.



Your Answer for Question 3:
